My 1994 Ford Tempo (automatic) cranks but wont start. I've tested the coil, replaced the ignition module, and some wiring tests but it wont spark. It started fine until I tried to install a remote starter (which I unhooked after it wouldn't spark) and now it won't start. What could be the problem?

You will need to double check all the wires you tapped into when you tried to install the remote starter. Has it started at all since?

It has not started since I attempted to hook this up. I have unhooked everything from the remote starter and it cranks but wont spark. It had no start issues before this except once in awhile would have to be put into neutral to start. I have double checked all the wires and everything appears to check out fine.

Are you getting the MIL showing on the dash? Is it definately a no spark issue? You are getiing fuel but no spark? The no start issue before is probably a fault on the Brake On/Off (BOO) Switch
BOO switch is wired to brakelight circuit. It signals the PCM when the brake is applied. The BOO input is used primarily by the torque converter clutch lock/unlock strategy. The BOO is located on bracket above the brake pedal we need to check this switch and wiring also could you please check we are NOT getting a spark and we ARE getting fuel?
