1994 GT/Auto with No Start/Normal Crank
To whom might be able to offer any help,
My wife was out driving our '94 GT/Auto a couple weeks back when the car stalled while waiting at a light. Before having the car towed home, I checked for codes, checked the reset in the trunk, picked up a new ignition module, coil and some fuel. No codes, reset not tripped and none of these items got the car back on the road. I had the car towed home and started reading through my copy of Charles Probst's "Ford Fuel Injection & Electronic Engine Control" which has been really helpful with my '86. After the "quick test", the manual said to check the Ignition system. Performing the TFI-IV electrical test I found that continuity was good between the distributor base and the block; there was battery voltage between PWR on the distributor harness and the distributor base KOEO; I was getting 8 to 10 volts between "start" on the TFI connector and the distributor base during engine crank. When backprobing the TFI connector at "PIP" I got a maximum of 2.9V during engine crank, just under the 3V to 5V acceptable range. When I backprobed the distributor connector at PIP A (to EEC) and PIP B (to TFI) I got a max of 2.9V to PIP A and 3.46V to PIP B during engine crank, so the PIP A was just below the 3V to 5V acceptable range while the PIP B fell within range. If the PIP is out of range, the book suggests a faulty Hall Sender, however these were barely out of range. Finally, I backprobed the TFI connector at "SPOUT" and got 1.4V at engine crank rather than the 3V to 5V acceptable range. The book said to check wiring to control module and if ok that the control module may be faulty.
I took the OEM and aftermarket Ignition Control Module to be tested at Autozone; both tested good.
I installed new Motorcraft plugs, Motorcraft spark plug wires and a new DUI distributor cap and rotor; no start.
I checked the fuel pressure at he rail; fuel pressure is right about 38psi with KOEO.
I checked that all fuses under the hood are good.
I disconnected one of the fuel injector harnesses and inserted a Bosch Noid Light; no light with engine crank.
I disconnected one of the spark plug wires and inserted a grounded spark tester, no spark with engine crank.
I ordered a Motorcraft Stator/Hall Sender assembly thinking that maybe this has failed and is not allowing for the injectors to fire or for spark.
Am I going down the right path?
Can you think of anything else to check?
Thank you for taking the time to read through this.
