Got a nice crisp, blue spark?

 

i feel like no...
maybe more of a yellow?
(going to double check now)

 

its blue

 

Well golly. I think there are a number of MAP tests, I would need to search it myself. Three wires? One ground, (to check), one 5V feed from the PCM, and the third provides the info to the PCM. I guess with a vacuum pump you can actually watch the voltage on that third...

I'm no wizard! 1/2 that post count is me asking the wrong question! I might be checking that ground, and the feed to it...maybe someone else might chime in...Your problem may well be there though, Idk...

 

could the map be running it so rich that it dies out? and then keeps it from starting due to being flooded?

 

Maybe. Is there a little "L" tube on the bottom? If so, does it look OK?

Yea, the map is one of the only thing's I've noticed can really mess things up. The puter' uses it to "rough out", how much fuel, then the 02 sensor fine tunes it..if I have that right.

 

i'll check it again but i took great care when i put it on the new 62mm tb

 

I've never even seen one on a TB. Anyway I might check the ground and the feed from the PCM....of course I new one won't help if there are wiring problems....which comes up allot.


If there is a "A" that might be ground. "C" would be the 5 volt feed. That's for my old Renix, but yours may well work the same.

 

its snowing now ha ha
but i cant measure it with it hooked up, but i can measure the pcm side (harness) and the map separately

 

also for fun

 

Changed map, started once, I let it run for a bit, then I shut off and now no start...

 

Went and got the fuel pressure gauge
Came back and started it, and it started,


Running pressure



Shut it off and wouldn't start back,
Prime pressure was about 30

 

There was a guy posting a while back who had all sorts of trouble with his Coolant Temp Sensor. (for the engine, not the gauge or fan). Maybe it was CPTSlackass. Anyway he needed to unplug it...and might have gone through a couple of them before he finally got her to work right. I think yours is still on the side of the block. If you have spark, it's flooding, and it's not the map I gotta wonder....

I just don't know but maybe that or the IAT on the intake would make it flood.

Also I might check spark immediately after it dies. I wouldn't expect a new MoPar CPS to fail, but your intermittent stuff sure is weird.

Did you check the ground and feed to the MAP?

 

I'll snap a pic of the wires, and you tell me what to test...
