2.5 cyl venture

well I tested the exhaust heat { on startup.} I found number one and three sleeping on the job. One hits sometimes. That's a real nice spot where the coils are. Is the resistance of the plug wires same on second gens? That's all the farther I got tonight. Don't have a socket to fit in hole till tomorrow for plugs. Way to tight a fit will have it turned down tomorrow. They run pretty good on two.

Rodney, make sure you take off the engine brace beside the front two cylinders. makers it mucho easier to get to the plugs....

well checked spark with a extra plug. I broke my tester. Little bitty blue spark hardly able to see it. So I pulled rear coils. Primary tests out good. Cant get any reading out of secondary at all. Not through any terminal or ground. Don't know if wire is shot or coil. Who glues wire to coil. Read a couple of posts saying test is wrong in manual. So which way is correct wire to igniter terminal.

Well I cleaned the sparkplug boots. Now I can get a reading through them. And got the coils to test out correct. Cleaned terminals at coil and next plug. Have 12 volts to coils. Cleaned the computer plugs they were not really dirty though. Any one have a computer for a 01 venture I could borrow to test it before I think about buying one. Or something else to check, Bike runs on two cylinders. Couldn't find my compression tester but with plugs pulled plenty of air. Also was looking at after market computers with 6 or 8 different settings cant remember which there almost 250 bucks. Want to make sure that's the problem before buying. All ready bought two coils I didn't need but that was my fault for taking a short cut.

Did you try switching coils between a good and bad cyl to see if the problem moves with the coil.

Next step after Jeff's post is to take apart the computer. Make sure the plugs going into computer are clean. Plenty of info here on taking computer out, apart and replacing deteriorating diodes. If diodes are toast, computer probably is too. If you are lucky, then solder new diodes and done!

 

And thanks for updates.

Well on a second gen there sealed. Tested pickup lead and have a good reading. So I bought a dynatek 3000 series ignition wont be here for a week. $215.00 dollars.

got a couple of those also

Fixed my spark problem tci worked good. Plenty of spark now. Ordered a color tune as think it needs more fuel to back cylinders. If I pull plug and put gas in cylinder warms up faster. So want to set combustion close to correct. Then will know where I stand. Set the rev limit to 7250, and advance to three.
