91 classic, cranks but won't fire. It's been outside and below freezing for a few days. I have spark at a plug and at the coil. Plug gap is a bit worn. I can hear the fuel relay click under the pass. seat when the key is turned. Next step?

EDIT: Got it going, unplugged the coolant temp sensor behind the dizzy.

if the reading is out of range it will adjust injector opening accordingly....did you swap one in?

edit: at 32 deg f the resis should be 5700-5900 ohm

I had trouble starting my 95LWB a little while ago. I replaced the ignition coil, amp module, ignition switch and IAC. Turned out to be corroded contacts on top of the ignition coil on the (-) side. I soldered new connectors and wires on, and cleaned up the terminals on both sides. Been running great ever since.

I put new plugs and wires on it today and it is running sweet. Went to put some gas in it, and it would not start at the pump. Got a jump and went home to find I was getting 14.15 volts at the alternator and only 13 at the battery. Checked voltage at the junction on the passenger firewall with ground on the engine and still had 14 but only 12.7 to 13 at the battery. Tested battery again by grounding the gauge on the AC pump and voila, 13.7V. Went to AB and bought a new negative battery cable this afternoon. Rotten ground was preventing the voltage from getting a battery charge. Will swap it in the AM.
