David, the first thing you need to look at is what is happening when it
won't start. If it has spark but won't fire then you want to check to
see if your injectors are spraying. If they are working then put your
hand in front of the tail pipe to be sure that the exhaust is getting
out (no clogged cat) when you crank the van over. If all of these
things are working and it still won't start then it is possible that
there is a sender in the FI system that is causing the van to flood
out. Most of the time if this is the case with your van, it is the Temp
II sensor on the thermostat housing. You can test for this by
unplugging it and then using a paper clip to jumper the two prongs in
the plug to each other. Now try to start the van. If it starts right
up then you know that it is the temp II sensor that has gone bad. If it
still won't start, try unplugging the oxygen sensor. The van will run
fine without it plugged in and sometimes they can fail and cause the van
to run super rich (flooded).
If none of these work, I would check your spark plugs for fouling and
proper gap and also your cap and rotor. If you go one thing at a time,
step by step, you will find the problem.
If you need any other help please let me know.
