Check the gas, could be water in it or drive the car with a fuel pressure tester connected to it and watch to see if you lose pressure.
Normal pressure while driving is about 30 to 40 psi

Just changed the 2.5L engine in my 89 jeep wrangler and the engine turns over but won't start it just backfires like the timing is off, but thats not adjustable on this engine. Where did i go wrong?


Have you checked the firing order to make sure the plug wires are in correct order. Sometimes an engine will run but rough if 2 wires are mixed but it could be that there's more than 2 mixed up.

Sounds like a bad fuel injector. Shop would need to run a contribution test to confirm. I must say, good detective work, good luck.

It does sound like a vacuum leak. Get a can of WD-40 and start spraying around the carb. It will rev up, and U can pin point the loose vacuum hose, are crack vacuum hose.
