1995 No Start
Hi Guys,
Got a 95 wrangler that decided not to start Super Bowl sunday, and hasn't budged since.

It turns over but will not start.

I checked the battery ground and engine ground which are both good.
The battery is good, and had a full charge - it's a bit low now from all my attempts.
I played musical chairs with all the relays under the hood, and all the fuses are good.
I pulled a plug and touched it to the ground and got spark.
I depressed the rail compression gauge nipple, and gas shoots out.
I opened the air intake and shot some starter fluid in it.

I don't have a check engine light on.

and the fuel pump and the fuel filter have both been changed in less than a year...

My next thought is the Crankshaft Sensor (which went bad a couple years ago causing the jeep to die in mid ride), but I read somewhere if there is spark, the Crank Sensor is good??

I don't have money to throw at random sensors so I'm hoping someone on here might have some insight...

Need to see hoe much fuel pressure there is. Rent or borrow a gauge from parts house. It literally won't start under 30 psi. It should be mud to upper 40's. I'd test that and the Tps.
What color was the spark?

Thanks for the tip uber. The spark was golden I guess, don't quite remember I wasn't paying much attention to the color.
If the fuel pressure IS low, what would you check next?

If the fuel is low then u would start easy and cheap. Filter. It could be dirty. A year is good. Then I would look into the pump and regulator.

I had a friend crank the engine and hit the gauge nipple on the fuel rail, and the fuel shot out with tremendous force. I don't have a fuel gauge, but my guess is the fuel pressure is fine.

Just replaced the Crankshaft Sensor, and there's no difference. She still won't start.

Just replaced the Starter and no luck :(

Replaced Distributor Cap, Rotor and plugs, still dead in the water.

compression test....fuel pressure test....

nickmac 02-09-2014 10:26 AM

I think the fuel pressure is good, what will a compression test tell me. I think the kit is like $40, that would be about the last thing I could afford... lol

nickmac 02-09-2014 04:50 PM

I think I've found the problem, I pulled the distributor cap and had a buddy crank the engine... The rotor goes around at a snails pace.

LJman06 02-10-2014 05:53 PM

well at the rate you're replacing parts who know what it will tell YOU.:cool:

The time now is 04:39 PM.
