Ok I have a 96 4.0l xj with a 5 speed trans just did a complete engine rebuild I have fuel and spark but it only cranks over. I have poured gas down into the intake to see if she will fire up and nothing I am not getting any backfire burp or anything through the intake so right now I'm totally confused. I helped my buddy rebuild his bout a month ago and it fired right up no problem at all so any help would be appricated thanks

Have you checked the timing?

ronnorman_6

Im pretty sure its in time right I alligned the marks right it goes diganal from cam bolt to crank bolt right and if the cps is bad I wouldn't have spark right

Xjtim

Fuel and spark, and no start? That's interesting...check for a ground cable/wire that is loose, or not attached.

CheapCherokee

check the ignition timing. did you put in the distributor correctly?

Lead Foot

You can still get spark of the CPS is bad. It just won't be in time properly. Change the CPS.

lukeincolorado

Actually you wont get any spark. No power will get to the coil if there is a major fault with the cps.
How do you know you have spark?

Lead Foot

Umm. Yes you can get spark with a faulty CPS.

Ok I have a Extra spark plug pulled the wire and turned it over this isn't my first rodeo and I has spark I finnaly pulled off the timing cover its in time right on time on the compression stroke and dissy is at #1 so now I'm totally confused on what to do or change

dragonlrd00

If the timing is right and you have fuel and spark you need to check compression i know you said its a fresh rebuild but things happen.

And yeah if the cps is bad you wont get any spark.

Xjtim

True..if valves are adjusted incorrectly, or not at all, you will have no compression, also during the rebuild, the piston rings should have been installed with the gaps of the rings all pointed away from each other....

ronnorman_6

ya i did that right i made sure none were pointing each other i made it like a plus sign

^ That. I just posted over in the OEM section with pics of the newer style distributor...

And actually that's after #1 cylinder. I believe the rotor turns clockwise, or does it? Either way, that pic shows the correct position.
