95 Wrangler won\'t start

I have a 95 Wrangler with a 2.5 liter 4cyl engine which I replaced with another used engine. Now it won't start. I am getting no spark. I just cranks. What am I missing? Thanks for any help.

Re: 95 Wrangler won\'t start

Internal Combustion Engines need three things to work air, fuel, and spark. Your not getting spark...are you positive you are getting fuel if so, check your coil, if not your coil...make sure your rotor is turning. If you are not getting fuel or spark check your CPS and your cam sensor I have had these go bad and never even checked to see if I was getting fuel just automaticly thought it was a spark issue when in reality I had no spark and no fuel. Check all your fuses.

Check ALL the fuses! This sounds really stupid, but my buddies 95 YJ wouldnt start for several days. It turned out to be the dome light fuse! I guess it was tied in some how, but I still dont know where.

Re: 95 Wrangler won\'t start

Assuming that you've connected everything back up AND the old setup was firing when you took it out ...you've got some defective part on the new engine.

I'm not sure what your engine needs to give you spark. The newer ones use a crank position sensor ...which I think is on the trannie bellhousing. The distibutor just triggers the fuel injector(s).

Anyway ...is your check engine light hooked up and functional? Is this an otherwise stock installation? If so ...check the engine codes. Check out this page. . It "may" point you in the right direction.
