Okay all, I changed out my fuel filter and oil drove the car (93 Stang 2.3) all day short hops then an 30 mile trip home. Went to leave 45 min later and crank but no start! Checked spark - Okay; Checked loose wiring: Okay (I just spent 2 days fixing the previous owner/bodyshop trash work in the engine bay); pressed the fuel relief valve and dribbling fuel. Listened for the fuel pump to come on with key in "on" position, no sound. Checked inertia switch: Okay; Rechecked pressure a bit more but still a dribble; Started thinking fuel pump but wanted to by-pass relay and send power straight to the pump, TA DA!!! Where is the relay???? One Alldata subscription later I found the ICRM (Integrated Relay Control Module) contains the fuel pump, EEC Power, Electric Fan AND WOT-A/C relays all in one convient place. WTF!!! You can't fix it. You must replace this $140.00 to $160.00 black box (Yes, it is a black colored box).
From research each relay operates independantly and is just HOUSED and GROUNDED in this sealed box.
Now the question:
Has anyone built a work around for this thing?
No but I keep this wiring diagram in case I ever decide to.
I'm sure a set of decent automotive relays could be used to replace the entire module and make it more serviceable. Not only that, but you could get rid of the ugly black box on the strut tower and relocate the relays to a less conspicuous place.

He has a very good idea. If you can figure it out, you can move them to a place not under the hood. I had the same problem, turns out I needed gas. So I have an extra ICRM and computer from a 93' automatic. It's possibly for sale if you need it. PM me and i'll see what I can do.

Thanks for the offer but I already had special ordered one.

I have my old one off and the new one on so I am going to disect the old one. I'll keep you posted on the progress of the "new" version. AutoZone got my new one to me in 24 hours and were $12.00 cheaper than RockAuto.

OKAY... A word of warning. Before I got the new part today I'd stopped at the gas station and refueled (no restart problem) and went to the salvage yard for some interior parts I needed to replace. I stopped turned off and went in to check in with the owner before heading out into the yard to go searching for my parts. About 90 minutes after turning the car off at the "mustang/ford" area the car would not restart.
This time I heard the fuel pump cycle on but crank with no start. I have come to the conclusion that I may have had more than one problem. This time no spark. I now have a new ignition module as well ($145.00 from AutoZone). If it happens again then the coil packs will be replaced. Always remember, old cars have old parts. More than one part can act up at once. Always be patient and have a reserve fund for repairs. Otherwise only buy a car with a really good warrenty if you can't handle the stress.

could be crank sensor from all the times you tried to start it. They are $140+. These 2.3l's are cheap to buy, but expensive to keep up with. My next Foxbody will cost me $3K just so I don't have to do anything but drive.
Intergrated Control Relay Module (Argh!)
