Fuel Injector Problem On Lincoln Towncar, Mechanic's Please Help?

Question

Hi, my 1993 lincoln towncar has been putting really bad and I finally found the problem (I thought) I was pulling the electrical plug In's that go to the fuel Injector's and when I pulled them off while running It had a very low Idle which was good meaning that the fuel Injector's where working, but I came to the very last two and noticed no difference In the motor so I thought the Injector's where bad and bought two new one's but It did not fix the problem they still are not working and I checked the wires and they are delivering out volts to them two Injector's so the Injector's can perform but these two are not working, I checked all the fuses and changed the fuel filter and the air filter Is clean

I was wondering what else can be holding these two fuel Injector's back from working? It's only running on 6cyl.

Any help would be great! Thanks

Answer 1

Sorry you spent the money for the injectors and they didn't help. That happens alot when people don't fully diagnose a problem. The problem could be that the cylinders aren't getting any ignition because the plugs aren't firing. You've eliminated fuel as the problem so it has to be ignition or compression. If the two cylinders that aren't firing are on the same bank, it is probablythe head gasket blown between cylinders. A compression test will reveal that. If the cylinders are on opposite banks it is probably the coil that serves those two cylinders.

actually appears like grimy injectors are achievable. "Clogged" is probably too solid of a observe in maximum circumstances, yet airborne dirt and dirt does boost and it doesn t take an entire clog to make a screw up engine overall performance. All it takes is for the airborne dirt and dirt to somewhat adjust the spray trend, tension or attitude of the gasoline that comes out of the injector nozzles and your motor vehicle can behave completely in a distinctive way. some injector purifier drinks can forestall such matters whilst some could have the skill to interrupt up the airborne dirt and dirt. yet while the subject has been left untended for a whilst, you could ought to bathe them amazing utilising pressurized cleaners or taking your motor vehicle to a keep.

Answer 4

the injectors that you replace did not need to be replace. you need to do an engine compression test. low compression reading will fool you that the injectors are bad. the MOST common problem on your town car 4.6 liters engine is damage headgasket. hook a compression gauge(tool cost 60.00) and do an engine compression test. reading lower than 70 psi. indicate problem

Answer 5

The computor has drivers that control 2 injectors each .
Have the computor checked. other than that it could be in the wireing harness.

Check for fire on those cylinders. Could be that they get fuel but no fire.
