Question about 1989 Isuzu Pickup 2WD
Just picked up a 1989 Isuzu pickup 4x4 2.6 and it seems like the exhaust valve isn't opening ( I say this because when i pull the spark plug it looks like there is wet gas on it but there is spark )and it mis/back fires on the 3rd cylinder back from the front.any suggestions ? the old man I got it from really never drove it I think it has moved from its parking spot maybe a handful of times in probably the past 8-9 months that I know of thanks

Assuming your 1995 Isuzu Trooper is using the 3.2 SOHC engine, the firing sequence would be as shown here.

Isuzu seem to have complicated things by changing engines, firing orders and even direction of rotation! As you can see, they've numbered the cylinders the other way than the 3.2L.
The Firing sequence for the 3.1 (traditional distributor) 6 cylinder is as follows -
If you take the distributor cap off, there should be a "No.1" formed on the inside. Stick a lead on this before you put the cap back on and go from there.
As leads are different lengths, you may have to swap a few to find the best fit.
I think 2 of them will look out of place - but that's the way it's designed. Just make use of clips for holding them neatly.
Thanks for using Fixya.

Did you sync up the engine properly when you reinstalled the timing belt/chain? It is possible to be on the marks and be 180 degrees off. Align the timing mark on the crankshaft then check the rotor position.If it doesn't point to number one wire terminal position roll the engine over until the crank lines up to the timing mark again. The distributer needs to be pointing the wire terminal that goes to number cylinder.Any other position is unacceptable and you can't simply turn the distributer to number one either You need to retime the crankshaft to the camshft making sure that the distrubitor points to number one and both valves for number one cylinder are completely closed.
