I turn it over and sometimes it starts, most times I have stop and crank it over again. Has anyone had this similar issue or think they can help diagnose the issue

 

More info. Test the coil and spark. Sounds like a cps though.

 

Assuming that this is about your 87.

You have a Renix XJ (87-90) By design, the engine is not going to fire until the computer (ECU) gets a signal from the crankshaft position sensor and measures that signal to indicate that 300 rpms while cranking has been met/exceeded.

Somewhat extended crank times should be considered a “characteristic” of your engine, rather than a problem.

You can upgrade the battery and battery cables--at least 4 ga., 2 ga. better--and buy a high-torque starter.

Be sure that all grounds are good. Remove them and freshen them. You cannot tell if the grounds are electrically good by looking at them! Renix vehicles are very sensitive to ground issues.

Other than that, performing basic tune-ups on a regular basis is important, (plugs, wires, cap, rotor, fuel filter)

The above suggestions are things that will help optimize start times on a Renix engine.

 

Fixed.

 

Lol at busted knuckle. My jeep takes about three to four seconds to start and the initial startup of the day is a little rough.

 

When I got mine back together I forgot to plug cps back in. When I did (with full.battery) it started in two cranks. Amazing! I figured it was due to the fact I cleaned all of the under hood electrical connectors.

 

Sorry for the lack of information guys. I turn it over and it will hesitate on the start i keep cranking and it will make a clunking noise then start up i never crank it for more than 15 seconds. Well Tj I will say that sounds similar to the characteristic of my engine, I've replaced my battery with 2 ga. wires, map sensor, and fuel filter. I have good ground, Coil and spark are good

 

Got good fuel pressure? The clunking noise is a weird characteristic

 

Clunk clunk clunk..... sounds like flexplate/converter possibly. Depends though. I can't hear the sound :-/

 

Here is the upload of the start up

 

Hard to tell but kinda sounds like a top end rattle like its lean or the timing is out. I can't really tell though. Hard to hear it. Is it like a diesel sound??

 

I feel like when it stops and turns over again the sound comes from the lower section of the engine. Not a diesel sound

 

Might have jarred the crank. Coulda messed up the caps and or bearings. Did your oil pressure change?

 

I replaced my oil pressure sending unit and it reads 30 before it gets to operating temp. and drops down to 0 which I thought could be faulty wiring but haven't determined what the cause is yet.

 

Uh ohhhhh. Sure hope its faulty... otherwise ya. You need bearings.
