What's missing ? Does it have spark ? Pull a plug wire off the vehicle an see if it has spark ! Buy a fuel pressure gauge an hook it to the schrader valve on the fuel injector rail . Is there fuel pressure ? Does the engine have compression ? No Start Diagnostic Basics EricTheCarGuy

We bought a 1992 pontiac bonneville, 65,000 miles on it. Changed spark plugs and new battery. Changed the IGN Module and IGN coil. Still doesn't start.


Make sure battery has a full charge. If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
Any applicable trouble codes? Your obd1, you should be able to check some codes, yourself, if there are any.

No spark runns fine then loses spark wait 10 minutes starts


The spark plugs receives power to spark from coil pack.Check the power at the coil pack and also check the voltage at the coil pack with meter.If the coil pack shows proper power as well as voltage then its fault in spark plugs.Otherwise its faulty coil pack.The coil pack receives power from battery.so also check the voltage of the battery it should be exact 12 volt.
If the battery shows low voltage then the battery needs to be re-charged.
Then check out.
Thanks. you can rate this solution and show your appreciation.

95 geo metro 3cyl. 1.0L no spark changed


Pull one or two sparkplugs and check them for moisture; not fuel, but for water beads.
I don't know how long your engine ran after losing coolant but there is a chance that you lost the head gasket and have gotten water into the cylinders.

Took spark plug wires off without labeling them


The ign coils should be marked. The front cylinders are 1 3 5 and the rears are 2 4 6..... the coils starting from the front is 1,4 5,2 3,6

1992 ssei, stalls when it warms up and starts back up again a minute or two later. Also have a esc, knock sensor code where is the knock sensor?


Knock sensor will not cause stall, but ign module problem will. Possible you have a bad ign module, but that will be a very expensive guess. Knock sensor is next to the oil filter.

Problems with my ignition Module (92 Pontiac Bonneville SE 3.8L)


Your Crank sensor is broken. You have to pull the Harmonic balancer off, it is behind it.
