heh... better than trying one and burning it out and thinking you have a bad signal when you don't... had a friend go through that. insisted his computers were bad and kept changing them because the noid light wouldn't light up.
did you get the forscan license? it's not hard.

Still a no-start situation. Because I still have the codes for the ignition system---even after installing a new PCM, I decided to order a new key switch because mine was funky and I also ordered a new start switch. I discovered that I could wiggle the key and/or the shifter and the radio would turn on. So--waiting for these parts to come in and see if some of the IC codes go away. Not sure if this will do much for the starting situation but then maybe it will. Had to go buy another car so now own a Suburban with the 8.1 liter engine. Hope to pull my trailer around with this car while messing around with the Ford. I'll let you guys know later in the week. Thanks

We have the 8.1 in an 2001 motorhome that runs really well so decided on another 8.1 Suburban also. This engine is getting hard to find unless you find one with 150K miles or more. If I didn't need a diesel for pulling the 8.1 would be my choice as a gas engine for pulling trailers and rv's. They are gas hogs as you say.

New injector harness installed today. So far I've changed the key switch, the start switch, the PCM, and the injector wire harness. Still no start and pulling these codes: PCM: PO262 (#1 high), PO271 (#4 high), PO277 (#6 high), PO280 (#7 high). OBD2: PO262 (#1 high), PO271 (#4 high). All four of these PCM codes are coming from the rear plug on the FICM. Could my FICM be bad even though it reads 47.5 volts? All pins look great on the plugs. I also have the codes in the IC: B1318 (battery voltage probably from cranking), B1352 (Ignition key in circuit fault), U1900 (communication), and B1360 (Ignition switch circuit open). Anyone have any ideas what to look at next? Thanks

You could try unplugging one injector at a time. May have an injector that’s shorted. What is the FICM voltage on a cold start before and while cranking? There are two sides to a FICM power and logic.

would this effect the other three injectors if I removed just one injector plug at a time? Ficm has always read 47.5 (koeo) and 47.5 while cranking. I have checked both readings at all stages of this no start. I'm using scan gage to read the FICM voltage. I'm using Forscan when I just turn the key to run position when I get all these codes. If I disconnect the batteries all injector codes go away when I do a KOEO but return when I crank the engine again. Hope this makes sense.

I don’t know enough on how the FICM board works to answer the effect on the other injectors. But atleast its free except your time. When you did the spool valves you made sure the coils were installed correctly along with the direction of the valve it’s self?
Maybe on Monday you could call Ed at ficmrepair.com and ask him a couple questions about your symptoms.

The power board has nothing to do w/ commanding the injectors to fire. The commands come from the logic board which fails fairly often also.
The fact that the codes are all from one FICM plug is justification for sending FICM to Ed for testing. He is honest and wouldn't sell you something you didn't need.
