If you are getting spark then it may be a fuel pump problem or fuel pump relay or inline fuse. Always start Fuel system troubleshooting by replacing the fuel filter or filters! You may be able to apply 12 volts from the battery (use a fused line) directly to the 12 volt side of the fuel pump and listen to see if the pump runs. Also may need to check that it is getting a good ground to the fuel pump. Then if the fuel pump does not run independently, replace the fuel pump. The fuel pump relay is computer controlled and several other things give the computer inputs which then controls the voltage to the fuel pump relay.

SOURCE: Replace starter on 1992 GMC Sierra pickup truck

First thing unhook positive battery cable, unhook main cable on starter selanoid and small wire on selanoid (there may be 2 small wires) There may be a bracket on front of starter that has to be removed, and then the 2 main bolts that hold it to engine block and it should come out.

check to see if you have your plug wires at the right location on distributor cap. If you don't have a digram they are as follows- right side 1, 3, 5 front to rear. Left side is 2,4,6 front to rear. #1 should be on the location at front of cap closest to intake manifold. firing order is 1,2,3,4,5,6. Hope this helps. KS

SOURCE: how to replace the magnetic pickup coil on a 1995

Remove the cap and mark the rotor to the distributor housing so you reinstall it in the same place.Remove the rotor from distributor and put it on a vise.On the bottom where the gear is you will see a roll pin.Use a punch and hammer and remove it.Spray some carb cleaner and spray it down the shaft and twist and turn the shaft while pulling up on the shaft.This will make it easier to come off.You might have to keep adding carb cleaner til it comes out.Then install the new shaft,gear, and roll pin.Then reinstall the distributor and align it to your mark.Good luck.

SOURCE: we changed spark plugs &

Here is the firing order diagram for the 5.0 liter (305), 5.7 liter (350) and the 7.4 liter (454) V-8 engines (note position of locking latches/screws between the 3 and 6 and the 1 and 2 terminals on the distributor cap). Let me know if you need the 4.3 liter V-6 engine diagram (hopefully not in a 2500 series truck) or if you require any further assistance.

How do you replace the ignition pickup coil on a 1997 GMC truck with a 5.7

A 1997 model should have the cam sensor mounted in the distributor with the plug on the side. Its held in with two screws. The older models were in the bottom of the distributor, and the distributor shaft had to be removed to take the pickup-coil out.
The job of the pickup coil was transferred to the cam sensor, then moved to the camshaft when the distributor was discontinued.

The coil is on top of the distributor cap. remove the top cover then the 4 small bolts holding it on. Unplug it fro the side, 3 wires... then just replace. Make sure to reinstall the ground wire that is located under one corner of the coil and held in place by the mounting bolt.

My safari 1991 have not electricity in sparks

The first thing a mechanic would check is for power and a ground signal for the coil. The pickup coil in the distributor sends a signal to ground the coil. The coil sends the spark to the distributor cap thru the rotor to the plug wires.

My Daughters 1991 astro van with a 4.3 was being driven and it was as if someone turned the key off . Now it turns over but does not fire up . ???? tried different effect.

Since you replaced the coil I would guess you have no spark?

If your getting fuel and no spark the first thing I would check or replace is the ignition module. It is located in the distributor. If you getting no spark and no fuel (no injector pulse) I would replace the ignition module and the pick-up coil. The pickup coil is the round piece under the rotor in the distributor that plugs into the module. The distributor needs to be removed (mark the base where it is held in place and the position of the rotor before removing so that it can be reinstall din exactly the same position!!) and disassembled in order to replace the pick-up coil.

I’m happy to assist further over the phone at

Its a 91 jeep cherokee 4.0 it turns over but will not start there is no spark. I have replaced the coil but still nothing

No spark usually is caused by coil (which you already replaced), ignition control module, or pickup coil inside the distributor. The coil and the control module are the most common. The control module is located just outside the distributor, you may be able to take it off and have it tested at the dealer. The pickup coil is inside the distributor, unfortunetly there's no way to test them. Also check plugs and wires if they haven't been replaced in awhile.

My car isn't firing. I changed my ignition coil, but distributor still isn't getting any spark(new wires,dis. cap,ign coil)

Without looking at the diagram on our model Is suspect the pickup in the distributor has gone bad. In the early type distributors the pickups are prone to go bad but ground the wire from the coil to the cap and remove the cap, have a friend turn the engine over with the starter for a few seconds, check that the rotor button is turning !
