    Checked and replaced both still no start las night. Tried to start it this morning and it fired right up. It's done this before. Took it for a drive, not too far from home, ran well. Jiggled wiring to see if I could get it to stop. Kept running. I'll try to start it again in an hour. Bet it won't start!

This is an easy one! :-) You have a bad solder joint in the DME relay, it controls power to the injectors and coil. Replace the relay or have a talented person resolder the pc board inside it. Probably best to replace.

Will bad knock sensor stop ignition from sparking?


I'm going way back into my alcohol erased memory on this one, but check your oil level sender. I ran into this problem many years ago and it seems like that was the culprit.

No spark or fuel on my 92vw golf


check voltage to both coil and hall sender. should get battery voltage across two outer terminals on hall sender. battery voltage at black wire on coil. should get 5volts[pulsing] out put on center wire on hall sender. if input voltage ok but out put not, hall sender faulty. coil and fuel pump need an engine speed signal to activate.

sounds like the distributor may be faulty and the timing is out.try moving the distributor.loosen off the lock bolt on the base and move it slightly.mark the original spot first.The other thing is make sure the plugs are the right type.platinum plkugs will not run in some engines.
the spark gap for the 5.2 is on the label under the hood.

I have a 96 chev 1500 4x4 5.7l which wont start. I checked the coil wire for spark to ground but there is no spark. What do I do next?


hook a test light to battery voltage. and touch the white wire coming out of the coil, have someone spin it over if light flashes and no spark replace coil. If light dosen't flash replace ignition module.

Car fails to start one day and starts the next.


I would check all the relays and the computer .
They could be over heating when coming on for a while then shorting out.
