I'm betting on a bad mains cable, or the braided ground strap that runs from the head to the firewall.
i changed all the grounds.
i still need to replace the power cable

CTS or MAT can be checked with a meter.
Double check the vacuum hose integrity from the TB to MAP, along with the electrical connection there.
ill check them tonight
So the starter will turn the engine over but then the starter will bog down?
if i just have the battery and accessories on the pump will still be priming.
The motor must spin ~300 RPMs before it generates enough current at the CPS for the Renix ECU to decide to start the motor. If the cold was keeping it from spinning that fast, yes, it would not start.
ok just wanted to update this...
i disconnected the battery and touched the - and + together for over a minute
connected and the truck runs PERFECT now starts perfectly drives great for the last 2 days...
does the computer need to re learn after you install a new ICM?
bump truck runs but has an intermittent cranking issue still..
it will crank then die as if the starter is giving out kicks it down and has barely enough power to get it going.
i dont think the power is getting cut from it because instantly its cranking again....but it will repeat this 2 or 3 times before it will run.. when it runs it runs perfect.
it will never do this on cold starts only after its been driven then parked and cranked again 5-10-15 minutes later.
im out of ideas?
can the manifold air temp sensor be involed? or 02 sensor?
dont say starter because its brand new.
yes exactly and it will do it 2 or 3 times before it actually starts running
this is the second starter in the truck and the old one did the same... (i thought it was a starter at first)
Is it a new battery? If not, it could be the real starter problem. Batteries on their last legs, can work perfectly one second then not the next. Put that volt meter on the starter when it is acting up on the hot cranking, and see if the battery voltage is dropping way down or not when the cranking bogs down.
I had what seemed like a good battery, bad CPS, then a new CPS but low CPS voltage, which required moving the cps closer to the flexplate, followed by a sudden battery failure (in steps), that kept me going for 2 weeks, before the battery crashed enough to be obvious!
might i add this is a fairly new optima blue top..
i had this in my 92 cherokee and it worked perfect.
