Question about 1995 Dodge Intrepid
1995 Dodge Intrepid - PRE OBD2
I have this same NO START problem as many others...
Began with tach giving readings not exceding 1200 rpm with strange 4000 + spikes.. Cruse control would not turn on or off at times and indicator light would only work sometimes..Had several episodes of excessive cranking to get it to start.. Stalling out while driving and even at freeway speeds.. Pulling the negative cable for 10 min. allowed it to start although with lots of cranking and put it in limp mode which required another computer reset to get out of.. Had thrown error codes related to cam and crank sensors which were replaced along with coil and manifold temp sensors.. Had the 9 volt power to sensors when key was on but the check engine light does not stay on with all the other idiot lights..
Seems the computer is not turning on the coil, injectors or fuel pump for a reason.. Find that reason and you will find the solution to the problem.. Seeing as that the computers logic states are a dealer secrete I have changed many parts in blind hope that it will fix the problem.. Relays, sensors and ecu computer.. Did a visual check of all harness potential wear spots like where it crosses over the power rack..
Could it be in the wiring harness inside the dash??
Could it be a bad ground??
Can an alternator that has failed cause the computer not to start??
Can a bad oil pressure sensor cause the computer not to start??
Can signal loss from the TCU or BCU to the ECU cause this??
Is there an undocumented kill if the ECU thinks it was in an accident??
I can ground the relay line from the ECU and the fuel pump runs and pressures up and the other relays turn on as well..
This crank but no start problem seems to be common with a lot of 1994-2001 Dodge and Chrysler owners.. All these systems have become interlaced with undocumented safety features that baffle the DIYer..If you have seen this and have fixed it PLEASE RESPOND!!!!
The PCM/ECM - engine computer controls the ASD relay as well as the fuel pump relay . The ASD relay powers injectors , coils > The PCM is not seeing an input for something that would not allow it to energize these relays .The best way to find the problem would be to hook up a factory scan tool an view sensor data paramitors . Does it have an anti-theft system ? Do you have a wiring diagram for the engine sensors ? Disconnect all that recive computer ref. voltage . A shorted sensor will bring down the ref. voltage circuit ,causing this problem .

Do a compression check, if you have lost compression on 2 or more cylinders try replacing the timing belt. If the compression is good across all cylinders and you have an alarm installed by pass the alarm by removing the in line fuse from the power line or cutting the power wire for the alarm.
