Took the head off my wifes 2.5l wrangler yesterday did a valve job new springs retainers seals gaskets CDR and replaced a bunch or corroded Vacuum lines and put it back together we didnt touch the crank or cam, left the distributor in but changed the cap, roter, plug wires, and spark plugs. we put the iridium plugs in it, It is getting spark but but wont start, It cranks fine but acts like it is not getting fuel it does not sputter at all. Any Advice would be appreciated need to have it running buy monday afternoon.
We did that and after several trys cranking you can see fuel in the intake manifold when you open the butter fly valve I dont here the fuel pump running but ti looks like it is getting fuel. sorry PCV valve I have a new EGR on order
just a note for when you get it running, change irridum plugs to copper. This shouldn't cause your no-start though. It will just significantly degrade the performance.
I would go to autozone and borrow the fuel pressure gauge, it is free if you leave a deposit. Pick up new copper plugs while you're there for about ~$6. Buy a new fuel filter while you're there if you haven't done so in a while (~$7). Check fuel pressure with the key in the ON position. this FI system is very sensitive to fuel pressure. The TJ fixed this issue...
Next, If your fuel pressure is good, I would next take the distributor cap off. turn the engine until the rotor points to #1. Take the number one spark plug out of the block and make sure the piston is in the correct position. This will check your timing.
Here is an update compression was low so i pulled it back apart did a ring job on it compression is back up timing is right or as close as you can get with a timing light with a cranking engine. got it all back together and it sputtered a couple of times now nothing. it is getting fuel you can see a puddle in the bottom of the intake.
I suggested he check it because he had the spark plug wires off.
what does that have to do with the timing? Timing is set and locked by the distributor location.. Wire placement or firing order can be effected by putting wires on in the wrong spot. But the timing will no change.
Verifying that the rotor turns is about all I would check with the dist.
