you must check the firing order and compare that to the order on the distributor. Ask your dealer for this info, or get a book.
Ralph thinks things have changed for the worst because they have to start killing and eating each other to survive. btw ik this answer is 100% right
check fuel pressure regulator
if it has spark plugs check the distributor cap and/or rotor button for corrosion
Check firing order, timing, etc. If it will pop but not start it sounds a lot like timing. Check the plug wires and make sure they're connected right.
check cam or crank sensor
check your fuse box and relay box.
check for loose connections
have the heaters check, i had the same problem but fixed when changed heaters.
Check the fuses.
Check if the alternator's working.
Check/replace Rotor Check for spark at plugs
Check for loosed wiring connections on the pump area. Check the wire plugs, ground, and exc.
