92 APV not starting

Hello from N.H. This is my first post, looks like a great place. I frequent Got Mud and 73-87 Chevy trucks.com as well. I have a 92 APV with a TBI 3.1 and 3 speed auto trans. Came to a stop the other day and when I hit the gas to go it shut off. Tried to restart it, cranks fine but no start. I happened to have a can of starting fluid with me. I pulled the air filter cover off and gave it a shot. Hit the key and it fired right up, but died. hit the key again no start. I repeated this procces a few times leading me to belive it was a fuel problem. Got it home, next day same thing it would fire on eather but wouldnt stay running. It sat for four days till I got a chance to look at it. Went out today losened the fuel line turn the key on and got planty of gas, could here the pump relay and the pump working. Tightened the fule line up and checked for spray from the injectors. Could not see any. Gave it a shot of eather and now it dosn't run that way too. Pulled a plug wire and have no spark now. Any ideas? I am a body man and do my own mechanic work 90% of the time but I don't have a repair manual for this rig, up until now its been the common wiper problem these seem to have, temp. sending unit, altinator, battery, & power stearing line type things. Will be getting one now. Anyone can email me direct if they want. [email protected]
Thanks in advance Harold.

Welcome to AF, most common issue for you symptoms is the ign module and dist pick up, check all the ign and ecm fuses first of course. Check all your harness conections also especially at the pcm, try tapping the pcm also, a comprehensive manual will walk you thru the steps for no sprk and injector pulse, but the dist. was common on these trucks.

Have checked all th fuses, and conections. Seem fine, wraped on the ECM with a screwdriver handle, still nothing. Going to put it on my trailer and take it to my buddies shop and run his modus tester on it.
Thanks for the quick reply. Welcome any more ideas.

$54.00 for a ingnition module fixed the problem. Thanks for the reply.
Funny when these rigs first came out I thought they were the ugliest rigs ever built. I still think they are fugly, but I love mine. It drives great, you sit up high like in a truck, you can load all kinds of crap in it. Takes 10' lumber, all my handy man / carpentry, ceramic tile tools / compresor when I am doing that line of work. Holds automotive tools parts etc. when I am doing that type of thing. Carries my 2 girls to all their sports events, vacations etc. Just over a year of onwership, $100.00 initial investment trade off for a plow bill. Still have less than $1,200.00 into it total after initial and over the last year of repairs etc.
