1987 chevy s10 2.5l tbi will not start. changed bad fuel pump works well now strong pressure to throttle body. change fuel pressure switch, oil pressure switch, o2 sensor, map sensor, distrib cap, rotor, electric part on dustrib, check for 12v to fuel injector good, check ground good, fuses good, ecm swapped. truck will run if using starter fluid.
That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel ste ... 1987 Chevrolet S-10 Pickup
Car will not start. car will run for a moment or two if I pour gas in the fuel injection manifold. The fuel gauge is pegged to overfull. all other gauges seem to work fine. Fuel gauge remains pegged even with the fuel pump electric wires disconnected. I believe it is a bad fuel pump relay or the the low oil pressure sensor switch is disabling the fuel pump relay. However I cannot locate the fuel pump relay?
The oil pressure sending unit will be the problem for that primes the pum when you turn the key to the on position. You will hear the fuel pump running for 5 seconds when doing that. If the pump is running when you have the key turned to the ON posit ... 1992 Buick Roadmaster
My chevy won't start.it's a chevrolet 2500 1989. I check all the fuse is good. I have a look at the TBI and I have no fuel coming out off the 2 injectors. the fuel pump is working and I have fuel going to the TBI. I try to put some fuel straight in the TBI and didn't work. now I'm wondering if it could be an electrical problem like the ECM or so?
Have you checked for spark. If it had spark it should have started when you poured fuel in. I'm guessing it might have a bad ignition module. ... 1989 Chevrolet C/K 2500
I am not getting any fuel to the engine. The fuel pump could be bad or there is not any electricity going to the fuel pump..Is there a fuse to the fuel pump on a 1978 datsun 280Z?
No dont think so as the pump is fitted to the engine isent it \015\012if not and there is no pump on engine or on eletric one under the bonnet then it must be in the tank .\015\012(But in 78 they were on engine)\015\012Find pump in ... Datsun 720
I replaced the fuel pump in my 1999 chevy silvarado 3 months ago and now my truck has died and acts like the fuel pump is bad, is there an electrical sensor that would keep my fuel pump from starting or could the problem be in the truck computer
Have a helper with you; have the helper crawl under the truck under the fuel tank. Turn the key to RUN and have the helper check for any sounds coming from the tank. If there are no sounds, then something is knocking the pumps out. ... 1999 Chevrolet Silverado 1500
1989 dodge d-series pickup. Truck was running fine and parked at work. At end of shift, the truck cranks but no fuel pressure in the system. Removed hose at filter and cranked. No fuel from pump. Is it certain the pump is bad or is it an electrical problem to the pump? How can I tell before I have to remove the fuel tank?
Are you sure there is fuel in the tank (you may have run out or someone - a thief - may have syphoned it without your knowledge). If the fuel pump is electrically operated then when you first turn the ignition key on you should hear the fuel pump wh ... 1989 Dodge Ram D-Series Pickups
1996 gmc yukon. replaced fuel pump 3 times in 2 months, finally running then it wouldnt start one day. cranked it over for awhile and nothing. sat 15 min it started right up, drove home shut off, then started back up. next day no start. just replaced fuel relay still no start, checked fuel pressure its at 0, is it possible the pump is bad again or could it be the clip for the power to the pump being loose or faulty?
This is a very common problem. GM has issued a service bulletin to replace the wiring connector at the fuel pump assembly on top of the tank. check the end of the plug for burnt terminals. the service bulletin states that these corroded connectors ca ... 2000 Chevrolet Tahoe
My truck just turned 200,000 miles, the fuel gauge all of a sudden started vibrating or bouncing back and forth, it is so fast and the bounce is such a short distance its almost hard to notice. shortly after this started, maybe two weeks, my fuel pump stopped pressurizing the line so now it takes about 3 seconds to start and i dont here the pump pressurizing when i turn the key on, do you think their just might be a bad electrical connection or a seal going out and not my fuel pump itself.
I think that the pump and the sending unit for the gas tank which includes the fuel level sending unit will be needed to be replaced to rectify the problem. \015\012\015\012Of course, the wiring should be checked out as well for wear of i ... Chevrolet 1500
Thought the fuel pump was bad, engine died but after hitting tank with mallet it started up and ran. replace fuel filter. started and ran a few min then died wouldnt start up. replace fuel relay still wont start. there is spark at the plugs. and it starts with starting fluid in the TBI. cant hear the fuel pump run at this time
If you hit the tank and it ran? The fuel pump is bad. By striking the tank you jarred the pump, causing what mechanics call "The last ride" Peice of sound advise, Replace with ac delco pump. The zone pumps go out usaly within months if not days ... 1995 GMC Yukon
There is no electricity coming to the fuel pump on my 69 280 SE sedan. When I run a hot wire to the pump, the engine starts and runs nicely. Where do I look for a bad connection or bad relay. Where does the juice to the pump come from? Thanks. John
Sounds like you need a wiring diagram-check all ur fuses-pump might be pulling too many amps and blew fuse-might need new fuel pump buddy-if you find a blown fuse-replace pump,relay,filter and fuse ... 1996 Mercedes-Benz C-Class

Fuel system My 2001 suburban 1500 died today at a stop light. After checking it over it appears the fuel pump may be out. I checked all the electrical fuses and relays and they were good. Also, i tried to listen for the "whirring" noise when you first go to start the vehicle but i can't here it. I pulled off the inline filter and with it off tried to see if it would expel gas when i turned the key on but nothing. I figure the pump has gone bad but want to hear of any other ideas before i dr
OK ! before replacing the fuel pump , check for the FUEL PUMP RELAY , usually located under hood where the MAIN fuses are , youre gonna need a multimeter to check for voltage where the RELAY sits , hope this helps , good luck AJ ... 2001 Chevrolet Suburban
The original problem was I thought the fuel pump went out, so I replaced it. Now it runs, but the fuel pump does not shut off. I can pull the fuse and shut it off, but it does not shut off on its own. A few weeks ago, I had and electrical problem, where I thought my battery was bad, but it was not. I think something is wrong in my main fuse. Last night I turned it on and turned it off, but the truck would not turn off, so I turned the ignition again and it turned off. Do you have any idea?
Hi\015\012\015\012Take a meter to your hot side of the coil, does it show voltage when the vehicle is off? If so, then that would be both problems. It can be solved by tracing down hot coil wire.I'm also guessing you might have a fl ... 2006 Chevrolet Colorado
I have a 1993 Plymouth Voyager. V6 3.0L engine. Sometimes it happens all day long and can sometimes go weeks without happening. I'll be driving the van and what I noticed only in slower speeds the van engine will cut off. All the electrical stays on just the engine cuts off, not slowly just like a light switch off, but it starts right back up again. I put a new fuel filter on it and 2yrs ago a new fuel pump. Could the pump have gone bad already?
Hello\015\012A fuel pump would not cause this type of shut down, a loss of spark would, this can be due to a failing distributor pickup coil or other things in the system that control spark, so the first thing you need to do is see if you have ... 1994 Plymouth Voyager
What powers the fuel injectors on this van? Is the fuel forced through the injector by the compression of the fuel pump, or the suction of the vacuum compressor? Or is the injector given an electric signal to allow the fuel to pass through? I ask this question because I am having trouble getting gasoline to pass through the injectors. I don't know if the injectors are bad (I JUST HAD THEM CLEANED FOR $250) or if something else is causing this problem. I feel as if I will be able to solve the pro
