1993 Toyota Camry. The vehicle quit while driving. It won't start. I replaced the Ignition coil because the resistance measurements were lower than spec. Now it has spark in all cylinders, all injectors are being pulsed and fuel pressure and volume is to spec. The spark plug are covered in fuel when I remove them after cranking the engine. I removed all plugs and installed them into each wire and observed the spark in each plug as I cranked it. I removed the valve cover to make sure the timing b

E300Td 1998 hard to start. Seems like it is not getting the correct fuel to injector pump. sometimes starts fine.

I have a 1994 ford f-150 5.0 engine. It will not start except with starting fluid. It has 45 psi fuel pressure, good spark to spark plugs, timing is dead on. It has no pulse to injectors while starting, when hit with starting fluid, it cranks right away & I get a pulse to the injectors, it will run all day until shut off & will not restart. Customer had replaced TPS a few months ago. At wits end!
It sounds like the (iac valve) idle air controle valve. When its running unplug it and if the truck shuts off replace the iac. it runs about $50 to $60 ... 1994 Ford F150 Styleside Supercab

Mazda MPV 2.6 1989 good ecm, good injectors (but no voltage), good spark, good fuel pressure, engine cranking, but won't start. If I put a little bit of gas on the air intake it will start. there's no pulsing voltage on the injectors when crancking. Fuel injector relay is OK but not providing ground to injectors (no ground avail on the connector).
You probably have a bad ecm. These engines used the same ecm that the injected b2200 used and they had a lot of problems with capacitors that leaked and damaged the etching on the ecm's circuit board. If you do indeed have 12V on one side of the in ... 1989 Mazda MPV
Problem with 1995 Subaru Impreza I recently changed the plugs and wires on a 95 impreza after taking it for a spin i decided to clean terminals on the battiery when i went to start over it would crank but it would not turn over.

I have a 87 nissan maxiam that will not start it cranks but has no spark and no injector pulse. The ECM doesn't flash a trouble code, but the anti-theft warning light flashes when the door is open but shuts off when the key is turned on until you start cranking the engine then it flashes again. I've replaced the crank sensor in the distributor thinking this was the problem. I don't know if the system is operating correctly or not.

I have 2003 Oldsmobile Alero 3.4L and it wont start. When I crank the engine it has spark and fuel pressure test shows 50-55 psi. Placed light in injector #2 connector and no light as I crank. Gynesis scan tool showed U1016. Earlier scan showed P1626c which is security code. I did the key on 10 minutes step to reset the security light. Any ideas why still no pulse at injectors?

05 jeep liberty 2.8 diesil. wont run. i cleaned the injectors, the where completly plugged. if i disconnect 1 injector and crank the motor over, there not much fuel pressure there. can the plugged injectors ruin the injector pump? the fuel filter housing has been replaced too. i have injector pulse too. but no fuel will come out of the injectors. it will run for a second if i spray starting fluid in the air filter. no engine codes at all, same goes for all the other modules in the vehicle. i don

I have a 1995 Oldsmobile Silhouette with a 3800 engine. The engine will turn over, but will not start. I am not getting any fire to the coal pack and the injectors want pulse. I have replaced the ignition control moduel and the crank sensor, with no luck. Could this be caused by the engine computer, or do you know of something else that can cause it?
Amke sure that any ground wire has not broken off on the wiring harness. There should be a grooup of wires that ground at the belhousing close to the starter. One of them is the ground for the ignition/coil. ... 1995 Oldsmobile Silhouette
My 1998 Audi A6 has a problem starting again after I have had it running and the engine is warm. It cranks but won't start. I brought it to have it fixed and they replaced the spark plugs (which were soaked with gas) and the wires. They cleaned the fuel injectors and and a fuel hose, but it still does this, of course not every time. The last time it stalled when I was moving and it had a hard time starting again. I had just replaced some stuff from an overheating problem 6 mths prior. An

1992 Chevy Cavalier RS 2.2 L 1G1JC5448N7285317 Looses ignition fire under hard acceleration and engine stalls. Has injector pulse while engine dies but no spark. Have changed crank sensor, ignition module, computer and have gone over every inch of the harness checking for a broken connection. Shows RPM on scanner while engine is dying. What have we left out or not checked? HELP!!!
What has to be done to restart? How do you know it is loosing spark? Can you get a fuel pressure tester? If so hook it up and tape it to the window so you can read it. If you can get back to me with this answers we can try to figure this out. ... Chevrolet Cavalier

I put a 97 engine in my 96 cavalier and it will not start. it has power at the coil and injector pulse but no spark. I had to change the crank sensor from the 96 to the 97 engine because it had the 3 wire conector. could this be causing my problem? please help.
There are several thongs that could cause this. Have you checked the ignition module? The wore harnesses or ecu could be different. A number of sensors on the new engine could be bad or incorrect. ... 1996 Chevrolet Cavalier

Hard Starting I have a 1989 Ford F 450 Super Duty 7.3 L DSL. The engine will not start when cranking after it is has sat for a while and the engine is cold. However, if you shoot three shots of engine starting fluid before cranking, it will then start. I am waiting for the glow plug liht to go off, indicating that the plugs are hot. I will not start on it's own, it always requires a couple shots of engine starting fluid. What can be the problem? I am not that familar with Diesel engines, If anyo

Check your temp sensor. if it's out of range it could be sending incorrect readings to the computer. Also check the white ceramic block on the drivers side fender back near the brake cylinder. It is a resistor that affects pump pressure on start up. ... 1987 Jeep Cherokee
