Try and change the fuel filter,if this does not help,have the fuel pump pressure checked,if it is a little low,then it will most likely be at fault,also,the fuel pump can loose it`s prime and make it hard to start,or a long delay in starting,and then just kind of half way run when started,then finally catch up,it does sound like the fuel pump,

1990 jeep wrangler motor has no compression


Take it back to the shop that did the engine overhaul. No compression at all? They did something very wrong. Does the distributor shaft and rotor turn when cranking the engine? Are you sure your compression tester is working and hasn't failed? Is it possible they got the timing for the crank and camshaft all wrong? Take it back to them and demand they fix it, if it truly has no compression. It will never start without compression.

My 1991 jeep wrangler will not start. Engine turns over fine. The engine is getting fuel and has fire to the spark plugs. I have already changed the distributor (cap and pop up coil), plugs, plug wires,...


Check the timing to ensure it is correct.
Check each cylinder for the proper compression.
Try starting the jeep with some starting fluid. If it starts with the starting fluid, you may have a few bad injectors, or faulty injector wiring harness.

Hard starting when cold ( engine cranks normally )


see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

1991 jeep wrangler not shifting into gear could this be clutch


I would first bleed the tranny lines, if that doesnt work then your tranny is out and need to get it replaced. FYI with Jeep Wranglers, It is better to get a new transmission then to rebuild them

Distrbutor to spark plug wiring


Hey there janandshane,

I've got a 91 Wrangler, lots of fun. Here's your info.

Viewed from above, front of vehicle on the right side, cylinder locations are:
6 5 4 3 2 1 for a six cylinder and 4 3 2 1 for a four Cylinder

The firing order is:
1 5 3 6 2 4 for the six and 1 3 4 2 for the four.

The distributor rotation is clockwise.

To find Top dead center (for wire to cylinder #1 on distributor), look for and line up the timing marks on the crankshaft (front of the engine).

Or, pull the #1 spark plug, stuff the hole with a cork or a rag. Slowly crank the engine until the cork pops out.

Pull the distributor off. The rotor is pointing where the plug for cylinder #1 should go. The rest of the wires go in the firing order clockwise.

That about covers it.

Remember: Good things come to those who rate. How about a nice FixYa?
