Just got this car for free and it sat for a long time in a barn where squirrels got into the engine bay and chewed wires I have repaired all wires to my knowledge without a schematic. Everything seems to now work correctly except the injectors. They have power to them with key on but do not pulse wen cranking over. I cannot find any wore schematic or info online. I know the 85 year is not as popular I would pay someone for help! Or pay someone for schematic! Thank u

Do you have spark?

 

I had Bishko manuals for my 96 98 before I got an OE printed copy.

You could always use a test light to check the fuel injectors for 12 V while cranking.

 

Spark and injector pulse width are related. They both get the trigger signal from the distributor, Usually in those years the ignition and the injection system work independently of each other, the ECM only controls the spark timing, so you can have spark and no injector pulse at the same time. Does the check engine light come on when you turn the key on? If not this indicates that ECM is not powering up. Check the reference voltage to the sensors, unplug the Throttle position sensor and check voltage at the reference voltage terminal it should be 5 to 9 volts depending on the year. Another thing thar can cause no injector signal is a out of range MAP. Sensor. Unplug the MAP sensor connector and see if it tries to fire. It will run like **** but it should try to start. I have seen out of range MAP sensors read in the 9000 ft elevation range which would lean it out so bad the it will not start at anything close to sea level.

 

There is no engine light when key is turned on I have 6v to throttle position sensor. Not sure witch wores over by the battery power up the computer.



NEVERMIND I DO NOT HAVE 6V AT TPS NOW AND I SWEAR I HAD ENGINE LIGHT ON BEFORE.

 

If your ECM is not powering up it cant turn on the fuel pump

 

If you have no pulse or CEL then its likely the computer is dead.Those distributors will spark with no computer input, so it may fire off with ether or gas down the intake. The easiest thing to check first are the fuses for the computer. There should be two in the box below the dash.

 

Ok I now have injector pulse and fuel pump. It tries to start but will not. I believe it is the map sensor on top of the engine with a 4 pin plug not 3 pin. The sensor has a vacuum line that goes too it and 2 wires go from it hard wired into a syloniod with another vacuum line coming off that it is located by the fuel pressure regulater. I cannot get this part at the store and everything I find online has a 3 wire plug and no syloniod. I believe 1985 was a one year setup and cannot find info. Thank u for all the help everyone I wanna get this baby going tonight lol

 

Also I used fuel pump from tbi 350 they were the exact same pump

 

That's a problem. TBIs run at 13-15 psi. I believe the regency has MPFI that needs 45 psi. That pump won't work.

 

Could you post a pic of the sensor?

 

switched back to original fuel pump seems to run better. I believe i need these parts for it to run right but not sure

 

I do not think that is a MAP sensor. It looks like a EVAP purge valve. I do not think your car even has a MAP sensor. I believe it a Mass Air system, and uses a Mass Air Flow sensor.

 

So do u think I need these sensors? I got everything done and fixed runs funny still and has engine light on. Also had a power steering line blow out and fixed it but can't get the system to bleed out. You have all helped alot on this I have never used a forum before it is quite awesome

 

All of the emissions equipment needs to be present or your car won't run right.

 

Does anyone know how the system works there's tons of vacuum lines and crap that are ate up. This must b a one year car or something I can't find any information

 

You mentioned earlier that you didn't see a Check Engine Light with the key on. We're you ever able to pull codes?

 

The check engine light was off because the computer wasn't on. I have it now and have not checked it yet I have been fixing other problems I'm getting close just not sire how all the vacuum lines ran before

 

You should reread post #2. Alldata could be very helpful with wiring diagrams and other service data. Spend a little $$.
