1999 Ranger cranking but not starting

[Payne@abstract-logistics.]

Truck ran fine last Wednesday, I parked it and didn't use it for 24 hours. Drove it the day after and it was misfiring, I took it to O'Reilly's and got new sparkplug wires and sparkplugs. That improved it but it didn't fix it, so I got it home and then took it back the next day to replace the ignition coils. I unplugged the battery while doing that for peace of mind and to clear the codes. After I replaced it and plugged all the spark plug leads back into the correct spots, I tried to start it and it wouldn't start. The battery was dead so I got a replacement, but that didn't fix it. I have replaced the crankshaft sensor and I have good fuel pressure. Sparkplugs spark when tested on the frame. I have also tested the injector pulse and it is good. I do have an aftermarket auto start, and security system installed but I have unplugged them both. The pats system does not appear to be engaged. Any help would be appreciated

Give it a shot of ether into the engine and see if it will fire off. If it won't, pull the sparkplugs again and check them. If they are wet with fuel they are probably fouled. If you have the old ones you can stick them back in, or take brake cleaner and compressed air and see if you can dry the new ones off. Then try it again.

It won't fire at all if all the plugs are wet with fuel. That can happen when messing around with it sometimes.

 

[I support common sense]

I think it might be your aftermarket mods, perhaps when you cycled the power it caused some change.
Don’t throw parts at it, go through a step by step diagnosis, you have spark, you have fuel, do you have compression? Have you checked for air flow, mice and things like to build inside the air filter box, look at your throttle body, check and see if your idle air control valve is opening.

Also make very sure that your wires on in the correct order odds are it would misfire at best and do nothing at worst if you put them in the wrong order.

I have cleaned the sparkplugs and tested them. I have good spark and good fuel, I've taken the air intake off so it will just directly get air. Still nothing

Then I would add a little fuel manually and see if it tries. Possibly for some reason the computer is not adding enough for a cold start.

I have used starter fluid and it will sort of shudder but not start
