Van just stopped running after traveling along highway for two hours. Apprears to have spark, will crank over, ignition switch has gear shift locked into park position, and battery has over 12 Volts. Anyway to check fuel pump, crankshaft sensor or ECM for operation without gauges or computer device?
Hello! in 1995 stored trouble codes used the On Board Diagnostic I software (OBDI)..Scanners will not work...The control unit LED can indicate any number of simultaneous component conditions by blinking separate codes, one after another...An instrument panel mounted indicator lamp will light and stay lit. If the lamp is on, or if a system malfunction is suspected even though the lamp is off, it is necessary to inspect the electronic control unit LED display. The LED display is on the ECM (ECU), which is located just below the RH side of the instrument panel. The indicator lamps operate whenever the ignition is On and a DTC is stored in the ECM (ECU) memory.
When an abnormality is detected the ECM (ECU) display blinks. The LED blinks a certain number of times, with the number of blinks indicating the number of the DTC. After the LED blinks a number of times there will be a two second pause and the LED will blink out the number of the next DTC..here are the codes..If there is a code send it to me...If there isn't a code I'll take it from there...guru.saailer

The ECM located under the RH side foot rest does not have an LED readout so I cannot determine any stored codes. The check engine light refuses to flash when the blue connectors under the dash are jumpered. To date I have replaced several ignition parts, but the van refuses to run. Plugs fire, but foul out and are wet with fuel. Timing belt and timing appear to be ok when checked.

Hello! Is the problem solved?...I do not see the additional comment you mention...but I'm dying to find out what you found!!!...saailer
Hello! no light on the dash with no response when shorting the connector is beginning to look like a bad ECU...I hope not. There are a couple of test to perform first...Got a meter? Set it to read 5 volts...Using two safety pins push the point into the rear of the in place MAP connector (mounted to throttle body)..Wire colors are Green/white...Yellow/White...and White/Yellow...Push one pin into the Green/White (Ground)....The other into White/Yellow...(+) meter probe to White/Yellow..(-) probe to Green/White...turn on the key...Just to on...Meter must read 2.4 volts...If it does not, move the + probe with pin to the Yellow/White wire...Must read 5 volts...Send a comment...The TPS is also on the throttle body...Wire colors are...Red/Black...Yellow/Blue...and Green /Blue...Use the same technique...(+) probe to Red/Black...(-) probe to Green/Blue...Turn on the key...Must read less than 1 volt (.85)...If not ...Move the (+) probe to the Yellow/Blue wire...Must read 5 volts...If neither results are as required let me know...Saailer
Ok I'll give it a try and let you know. Thank you!
Replaced the distributor and car started right up. Must have been a bad sensor or ICM module. Thanks for all your help.
