Will a cold start injector prevent a motor from starting ?
It doesnt seem possible but im here to ask the gurus.
Thx

LOL sorry.
Its a 91 FJ80 with the 3fe
If you have been following the saga....
I did a mild tune up plugs, cap/rotor, wires, pcv, oil/filter and sprayed the AFM with brake clean. After that the beast wouldnt start.
I tried replacing the AFM, The circuit opening relay, the Coil/ Igniter all with no luck. I do have spark and I have verified the plug wire placement on the cap about 50x.
Rule number 1: Spark and Fuel The Given: Spark
Try spraying starting fluid in it, sometimes it helps whatever you did get back to normal. As a rule, there is no reason to spray the AFM with brake clean IME.

I should note that the reason I cleaned the afm is that a pint of oil dumped from it when I pulled it to do the tune up.
I actually did spray starter fluid in the other night and it still didnt start. But I have spark ? What in the heck am I doing wrong. If the ECU was not working the CEL wouldnt come on correct ?

The CEL should come on with ignition on. If it does, and you have spark, it's probably ok. The AFM shouldn't have affected anything, cleaned or not. If it's not starting after plugs and distributor... How are you cking spark? Using the coil wire or a plug wire? If it's the coil wire, pull a plug wire and try for spark again. Pull distributor cap and make sure you have a rotor/in one piece/proper rotor/proper rotor orientation.
If the ignition is working properly, the truck should run off starting fluid for about 20 seconds or so. If it's not, you have a spark problem. Is it possible to put the cap on 180 out of alignment on that motor? If you have spark, you then need proper spark.
You might also want to see if any codes are stored.

So if the CEL is on the ECU has power correct ?Im checking spark by pulling a plug and grounding it while cranking. I have done this to all 6 plugs. The rotor only goes on one way. The rotor and cap are new. I did even put the old cap,rotor and wires back on just to check if the new ones were bad. Any chance anyone has a picture of the cap and wire placement just to check for a 51st time ?
Oh and no codes now. I did have one when I left the afm disconnected on accident. I reset the ECU and now its clear.
If you have CEL, spark and able to clear/find no codes, ECU is not the problem. If the wires are properly routed, you should be able to run off starting fluid. If you can't get it to run but no codes, that's usually an indication that you need to look at the wire routing again. Stock spark plugs with the screw caps on them? Did you pull the plugs and look at them for fuel? Plugs are properly gapped (grounded plugs don't fire well)?

Someone post a pic of the wires and cap for me
please The plugs smell like gas, and like starter fluid when I pull them.
If the plugs arent grounded how would they spark ? They are new plugs gapped at .044 I dont think .001 should make a difference.
