What would cause a 1991 s10 to not start back up


Replace the fuel filter,could be dirty fuel injectors.Check air filter.Also could be a clogged catalytic converter. Bad Fuel pump relay.Your fuel lines could be clogged,blow them out with a air compressor.Maybe try blowing it out first,cost nothing and may be the problem.

Ignition issues


Trying to diagnose others work can be difficult but have done it many times. First I need to know basically at this point if you are getting power to the dark green & orange wire at each injector as well as the dark green and orange wire at the coil itself. If you have an ohm meter check to see if you are getttting continuity from that wire at the coil as to any of those wires (dark green and orange) at any of the injectors. Below is a picture of some relays under the hood. The one with the red arrow is the auto shutdown relay which will cause no power to all those dark green and orange wires. You may still have fuel prssure but this will shut down power to the injectors as well as power at that wire to the coil. The other relays that have the x out mark are needed but the one with the yellow arrow is the A/C clutch relay. I'm not 100 percent sure so check the numbers to see if they match. If they do swap those 2 out to see if it may be a relay issue. This is what I would start at first. Start from point "A" the basics (this test) and go on to the next step. There are fuse links as well but lets start here. Feel free to email me directly for any other tests if needed at csautomotivecars@att.net and I will be happy to try and help. No there won't be a cost to you but do remind me of what's been done so far as well as the model and engine size. Hope it's something this simple for you...

Engine cranks but won't start


I firstly would check relay. You can use an ohmmeter to check the resistance of the relay. If you get a reading, it is good, If not it is bad. Than disconnect fuel pump wire harness and do the same.

Help w 1994 chevrolet truck


This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.
