1989 Plymouth Voyager no start

Hi:
It's hard to say what causes things anymore. I doubt the radio did it, but there body control modules that run many things and can go bad. If you are getting spark, did you check for fuel pressure? Can you hear the fuel pump run for a second when you first turn the key on?

Let me know.

Ok:
There are three different options. Here they are

TBI 13.5 to 15.5 PSI

MPFI (non turbo) 46. To 50. PSI

MPFI (turbo) 53. 57. PSI

If you have questions, let me know.

Hi:
In the 70's Chrysler used a vacuum switch to indicate when the person needed to back off the throttle. When the vacuum would drop in the engine, the left signal light mounted on the top of the fender would light up. I guess that was there idea of a way to improve fuel mileage.

Regardless, in the late 80's the term shows up again, "Fuel Pacer" and it's hooked into the starting system. The only thing I could find is an electrical schematic of how it's wired, nothing on it's purpose. I have made a copy for you to look at while I talk to another mechanic to see if he knows its purpose.

Take a look.... like on a map, go to B-5

I don't know if you will be able to read it because of it's size.

Let me know what you think and I'll keep digging.

Joe

Sorry. I had a feeling you may not be able to make it big enough. I have emails to two great mechanics here regarding this issue. I feel confident they will get back to me, but it may not be until tomorrow. I will let you know as soon as I can.

Joe

I just wanted to let you know I didn't forget about you. I have been through three mechanics and no one has heard of one. I assure you I am still looking.

Hello Aarno

Please tell us the size of your engine in liter.

Jacobandnickolas and I have been discussing this..... If you don't mind if you would check a couple of things.

Fuse 13 and when you check it please use an ohm meter as sometimes it may look good but not.

Next - I know you said you have a spark. So we are all on the same page... Please do this again - pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Should last for about 7 seconds.

If you are getting good spark then spray some starting fluid in the throttle body and try to start it and see if it tries to start then.

Also, lets try to check the codes on the car.....I know it won't start but still go through the procedures and see if it blinks codes and let us know.

ON-BOARD DIAGNOSIS
ENTERING ON-BOARD DIAGNOSTICS
1. Start engine (if possible). Move transmission shift lever through all positions, ending in Park. Turn A/C switch on, then off (if equipped).
2. Turn engine off. Without starting engine again, turn ignition on, off, on, off and on. Record 2-digit fault codes as displayed by flashing check engine light.
3. For example, Code 23 is displayed as flash, flash, 4 second pause, flash, flash, flash. After a slightly longer pause, any other codes stored are displayed in numerical order.
4. Once check engine light begins to flash fault codes, it cannot be stopped. If you loose count, it will be necessary to start over. Code 55 indicates end of fault code display. See FAULT CODES in this article

Please let us know what you find.
