    blinkers wtf

    if the hazards work and the turn signals don't. try moving the turn signal arm(on switch) a bit more up or down and see it that causes them to work, if so, the contants in the switch may be bad. are you on the brakes when they don't work??

    86 SD 5.0L problems

    the MAP tells the computer what engine load is and adjust fuel accordingly(as well as using other sensors). have you had a chance to test the fuel pressure?? unplugging the line caused a vacuum leak so that would lean out the mixture. have you tried plugging the hose that you...

    86 SD 5.0L problems

    i looked on the wiring diagram for the 86 and it shows a MAP sensor not a BAP sensor. do you have a vacuum hose hooked to it?? if not try hooking manifold vacuum to it. if you do have one hooked to it then check for 15+ inches vacuum. the 93 uses a BARO(simular to BAP) it does not use a vacuum...

    just wrote this on a dif thread. 22 - KOEO: check Vref voltage to battery NEG key ON, should be about 5v. if so, check Vref voltage to NEG of sensor, should be same. if not, perform voltage drop test on ground circuit. if you have 5v, check sensor voltage should be 1.59 at sea level, 1.56v at...

    with just full speed working, 99% it's the Interval Governor. check power on W wire at wiper motor wiper switch LOW or INT. if no power, check for power at Governor on BR/W wire Pin9 with key ON and wiper swt in LOW. and power at DG wire Pin10 when set to interval. if you have power then...

    blinker problems......

    as you probably have seen: the turn signal are powered by fuse #5 15Amp and the hazards by fuse #1 15Amp. since your hazards are not working either: check for power at the hazard flasher(on fuse panel). if power, check for power at hazard swt (Wt/R) with flasher jumped. if power present -...

    Tested Code Puller

    22 - MAP or BARO out of range - Disconnect sensor, key ON, check Reference voltage should be 5v. if ok, turn key OFF, reconnect sensor, key ON, check voltage on Sig wire of sensor. should be 1.59v at sea level, 1.56v at 1000 ft, subtract 0.03v for every 1000 feet elevation. 12 - Cannot...

    Non-Mustang Car Help

    for a 92 GM just use a paper clip. jump the top right hand 2 pins(A &B) in the connector and count the "check engine" light flashes. (easiest vehicles to check codes on) should show code 12 then anyother codes. code 12 - 1 flash, short pause, 2 flashes will show that 3 times then anyother...

    A gutless 94 gt! Here are the codes... What do you think?

    here's a write up i did awhile ago: to check the EGR valve: bring the engine to normal temp. connect a vacuum pump to the EGR Valve apply 5in vacuum to the valve. if engine stumbled or died then EGR Valve and passage(there is a passageway through the intake and tube coming off header)...
