Plymouth Reliant Repair Questions and Answers

Question: 1991 Plymouth Reliant mile: 143,833. The speedometer stopped working. Nothing is digital. Everything is completely basic. Nothing powered. I looked for a cable behind the dash. Found nothing. Not even anything close to a cable. Looked AGAIN for anything that looked like a sensor or (anything) NOPE. Looked around the engine for a sensor or cable. I'm pretty lost now. O.K. I bought the book on the car and it sort of helped. It told me to replace the cable. Went to buy one. The mechanic there said it should be a sensor. Possibly just corroded. LOOKED and LOOKED. Just can't seem to find the dumb thing. Found something. (This will be interesting to explain) here it goes... I found a wire it connects to a big round cylinder. Located closest to the windshield (under the hood) on the left hand side. (It's located way up in the hood, I mean right next to the windshield, not even close to the transmission right behind and to the left of the air filter) Now, the cylinder has 2 wires going into it. 1 is black colored, that one looks really clean and inserts into the cylinder. 2 pink colored, simply has a clip, and slips onto a L bracket (pretty small). Went ahead and unscrewed the pink one. Cleaned completely. No more corrosion. Reconnected. Wow! The speedometer wants to work. Where can I find were the pink wire goes. It should go to the transmission. But where? Can I get to it without dropping anything off? Like the cover of the transmission? I really need help. (Can you tell)? I know you two get a lot of goofy questions. This will be one of the best. Using cylinder as a description. Please help me out after you get done laughing. Thanks guys!

Answer:  We are not sure what the big round cylinder is or what the pink wire is about without having the car in front of us. However we feel your problem is with the vehicle speed sensor. It should be located on the transmission tucked underneath the motor very close to the passenger side axle. If the wires have come off or are corroded, this could be your problem. If the wires and connectors look okay, then most likely, the sensor is bad.

Question:  1993 Plymouth Reliant mileage: 135,500.  Dear Bob and Ken: When driving my car I can smell unburned gas fumes in the car.   I noticed that it only does this in the afternoon (lunch time) and my drive home versus in the morning when it is still cool outside.   I live in Phoenix, Arizona, how cool can it be.  I thought it may be the charcoal canister, but the car only has around 35,000 miles on it.  Any suggestions?  Thanks,

Answer:    Check the fuel rail that supplies fuel to the injectors.  It may be leaking.

Question:  1992 Plymouth Reliant mileage: 104,000. Please tell me if you can where the transmission modulator hose goes. I found the hose that attaches to the trans modulator; I think that is what it's called. It is long and it could go just about anywhere in the engine compartment. The problem is the car wont shift into 3rd gear until 47 mph. I looked everywhere for a place to plug this hose in and I can’t find a place to plug it into. I looked everywhere on the intake and found nothing. I would buy the book on the car but it is way to expensive and I want to just fix it and sell it. I appreciate your time and thank you very much.

Answer:  A Mitchell auto repair manual will have diagrams showing the vacuum hose locations. The manuals also give step-by-step instructions. Visit our Repair Manuals page to learn how easy online manuals are to use.
