cut wire(pic)

[jameswemm]

anyone know where this cut wire goes.been checking grounds all morning.at 5500 rpms my car nose dives till i change gears.right when it starts boosting good it dies.its like fuel is completly cut till i change gears.well any way heres the pic.on my way now to go get new plugs and wires. thanks.

is that wire coming from the alternator? it's hard to tell from that angle.

 

[jameswemm]

no it comes from the wire harness the two wires for the alternator come out of .at the bottom of the pic.

 

[jameswemm]

ive noticed today that every time the car cuts out the ecu clicks .so i have taken the ecu out now to check it.any coments on either of these problems would be helpful .thanks

 

[jameswemm]

do you think this is bad

That ECU has capacitor leakage that has now spread. Time to get it fixed before it stops working for good.


The loose Yellow wire looks like it might be the one to the power steering pump pressure switch.

not to change the thread subject but i dont think this ecu is working right.is there any one on here that repairs them or do i have to buy a new one.

Dave Mertz. He is awesome to deal with, and has a very quick turnaround. While your at it, if it is an eprom, get it socketed. [email protected]

Basec on the CPU code on the processor in the picture I'm willing to bet it's a non-EPROM MD166262 ECU.

[jameswemm]

yea its non eprom ,md166260 .getting price from dave(just emailed him thanks) and also looking around for an eprom ecu.

 

[steve]

yea its non eprom, md166260.

Assuming it is for the car in your profile it's been changed at least once aleady. That's the number for the FWD ECU.

Damn steve, you almost scare me at times with your knowledge of these dsm ecu's.

 

[marcmsj]

from the ecu pic, i can also conclude that he is right handed, once owned a pet fish named frank, and had spaghetti and meatballs on october 8th, 1983.

what are the advantages of eprom over non-eprom?

Simple answer, the EPROM ECU can be rechipped giving you full control over the way the ECU behaves.

not sure how many ecu's its been thru.bought the car 4or 5 months ago for a steal,and have had one problem after another(ive put 1,000 dollars in it since i got it).hoping to be driving it on the road in a couple of years(or it seems).oh and my pet fish was named hethcliff,oh so close though.
