I just purchased an 88 Trooper from a friend. It has the EFI 4cylinder engine in it. The trooper had been sitting for about 8 months with out being started. It has new plugs/wires/distributor/rotor button/starter. It is getting fire but I can't seem to get it to crank. It has started to crank a few times when we completely covered the throtle body. I have checked all the fuses and I can't figure out what is going wrong with this thing. Input would be greatly appreciated.
