what i did was completely grind down the engine ground. i had a friend try to start the car and nothing. i was jiggling the ckps pos sensor and it started! i have tested EVERY wire in the engine bay and know it was not because of a loose or broken wire.

this is what i think is going on: i have a frankencar ram air intake. my stock intake snorkel is gone so my map/baro (could be wrong, i looked at it quick) sensor hangs down close to the ckps pos sensor and the tranny gound wire i put in. i also have a 4ga wire for my amp that runs near those wires as well and a ground wire from starter bolt going to engine ground, all close in proximity.

when i moved the ckps pos sensor out of the way of the other wires, the car started. i think i am having some kind of magnetic/electronic interference that is throwing all the sensors off and causing the hard starts. i have also read that the coil packs, when they start to go, can cause radio interference and throw sensors off. anyone hear of this? i have 160k and still on stock coils.

tomorrow i am going to move everything away from one another, making sure my ground wires arent too close to the sensors and add a ground to the bottom bolt on the tranny.

when the car started, it ran incredibly rich. do i possibly have something else going on here?
Im confused on how u cd be gettin interference. All these wires SHOULD be shielded. U sure the harness good. Or maybe starter amperage causing a high spike for EMI near CKPS since u grounded it in close proximity. Move the grounds and see what happens.

GLad u got that bish started tho..hell yea man! lol

thanks cashoit, im confused as well but there was definitely a difference when i moved the the wires away from one another.

Not sure if this will help anyone but I had hard starts and poor idle. Opened the hood to check everything stated above still no help till I heard a slight air leak coming from the IACV. Turns out the Idle control screw had backed out full open. Closed it down and seemed to fix the issue. Five starts in a row with no lag . I'm letting it cool down now to try it cold. Hoping this sloved it. Will update later.
