Help!!! 96 Ranger 2.3 Rattling in idle, stalls
Hello Guys,
I have a problem with my little truck:
-First when you attempt to start it it stalls immediately
-After few attempt and constantly pumping gas it will start and idles very rough (after a warm up), Backfires and exhaust gets cherry red
- have p1504 and p0122 codes
what I've done so far:
- New fuel filter, pressure is good
- Checked all Fuses
- Replaced timing belt 3 times
- checked the vacuum the best I could
- checked wiring from TPS and IAC to PCM
- Checked output on TPS (left wire 5V, middle -1.0V -closed, 4.5x - full open, right is nothing 0)
simmilar to this
I've spent countless hours online and in the garage trying to figure it out. Would appreciate any input.

I did 3 times. That is what I thought first.
I removed bottom pulley and made sure it is seated properly. There is only one way to seat it. Then I was using the engine block marks instead of belt cover marks. Rotate twice using the wrench, then rolled back in 4th gear. The crankshaft pulley was only half-tooth off, Oil pump and camshaft right on the mark.

My bad I meant the camshaft is half tooth, while oil pump and crankshaft is DOC
Now I am looking at the IAC valve it looks like the rubber valve inside got stuck on closed. Is there anybody who can let me know how it should work?
I connect it straight to the battery (since reading on the harness was 12V) and can feel solenoid move (tried to switch + and -), but the rubber valve is still between two holes. I am unable to move it with screwdriver

I guess will wait till tomorrow, $150 at AZ
thank you ccosgrove71. I unplugged the MAF and truck started. It was trying to stall, but after it wormed up, was running allright.
One thing that still bothers me is exhaust is still red. You think it is injector got stuck open?

Ok I guess I need to do the followup and share the knowledge!
First - Thank you for your help and time that you invested in my problem. I really do appreciate it.
And now solution to my problem: Since truck will run just fine on break cleaner and exhaust gettin red hot after 1-1.5 min we decided that it was timing. After another attempt to change timing belt my buddy pointed at the crankshaft pulley. The notch was 3 times bigger than alignment pin, so the knock sensor did not know which position the engine was in.
I will skip my journey to the junk yard, just wanna let you know that advance and autozone don't have those pulleys for 4cyl, but they have for V6.
PS anybody needs a computer? F67F-12A650-VA writing ZZQ0
