My 89 Ford Taurus SHO wont start. it appears that my fuel pump does have that," second or so on time " when turning the key on.

I tested the front three plug wires for spark. they did have spark. I checked fusible links, fus

I have a 2003 Oldsmobile Alero 3.4L that wont start. I have done fuel pressure test 50-55 psi and plugs have good spark. However when done light test on injectors there is no response so there is no pulse. Gynesis scan tool shows U1016 and earlier scan showed P1626c which was security problem. I have already performed the 10 minutes key on reset for the security light. Any other ideas why it wont start and/or why no pulse at injectors?
Is the security light staying on ?Usually the engine will not crank and you have no power to the fuel pump if the security system is disabling the car.No injector pulse but spark would point to the computer since both use input from the crank ... Cars & Trucks

I have a 95 suzuki sidekick jx and it wont start. it tries sometimes but wont start. it has good spark, 180psi compression, has fuel, timing is good. if i hold the throttle wide open it will start and run extremely rough. the spark plugs turn black after a little while of trying to start it. i know that means to much fuel. but the fuel pressure is correct and the injectors open and close like they are suppose to. can you think of anything to try to test? thank you for your time
My first guess would be a leaking fuel pressure regulator or a problem with the injector grounds. The injectors may be "on" too much.Is the check engine light on when you can get it running ? ... Cars & Trucks
1984 300zx non turbo......the car was running fine and then it wont start. it has spark. and i disconnected the fuel pressure regulator and turned it over and fuel comes out of the fuel lines going to the injectors. The car turns over just no spark. i noticed a little leak in one of the fuel lines that runs into the fuel regulator and the regulator has a hissing noise but i couldnt find any holes in it. I am guessing that the leak in the fuel line wont let the fuel system pump up to pressure and

3.1 runs fine then wont start if i turn it off at operating temp. Here's the thing though. in the no start situation it has fuel pressure on the fuel rail and fire at the plugs.THe computer has been replaced.ok so lets recap has a new radiator (no sensor) has a new computer (ecm/pcm) has fuel pressure on the fuel rail, and has spark! could it be timing belt? no because it runs fine no backfire through intake or exahaust. is it the ignition module? no theres spark! is it a fuel problem? no theres
HI, ok lets address each issue as your asked 1. Timing belt: since this engine uses a timing chain and it runs fine for the most part its unlikely to be the cause. 2. Ignition module: well the module not only sends the signal for spark timing but it ... 1990 Chevrolet Celebrity

1999 Nissan Maxima wont turn over. It cranks, but wont start. It isnt the battery cause its new. My friend said it may be an electrical problem or fuel pump. How can i determine if i am getting a spark? My friend tried to start car and he did something with the fuel line to determine if it was getting pressure and it was. Not sure if it is enough pressure. He also used an older computer but it was only giving the error code for emissions. Any ideas?? Thanks.

During the summer time it will cut off sounds like it is loosing fuel pressure will turn over, but wont start back up until at least an hour later. Drives perfect during the winter time no problems, replaced the ignition coil and ignition module several times, distributor pick up, fuel pump twice, fuel fiter, emergency fuel pump cutoff, fuel pump relay, spark plugs, plug wires twice, checked the fuel pressure on the fuel rail, it puts out 40 psi on idle and does not go below 25 until you shut it
What causes this is ussually the oxygen sensor. It works when the engine heats up and if its no good, it will run your engine lean or even shut it down. check them and replace them. They should be done every 2 years. ... 1991 Mercury Topaz 4 Door

You say you have fuel but is it getting to the cylinders? It may very well be a timing belt problem (in which case . . bigger headaches) Try a little starting fluid in the intake air tube. You may narrow it down to a crank sensor. Hope this help ... GMC G3500
