i hope this problem happened to you,but you fixed it..

found out that my shifter was on drive.. so now the car cranks again,
I bypassed the fuel and its running.. the op switched it from the middle to the far right towards the driver. but still no starttyyy. im getting spark im getting fuel from the bypass test.. but the car still doesnt turn on....

[e30_3I8I]

it looks like the injectors arent working now...

I installed m50 injectors.
The car was working with them.. I just have no idea why a car would randomly stop working.

Check the connecter beneath the intake manifold

what do you been by checking? the car was running 2 days ago. It randomly stopped when my brother was changing the rear brakes.. he said he was starting the car to adjust the brakes and to check the if it holds while on drive.
And later that day he tried starting it and it didn't... its really random.. I check ohms on the ecu pins 47-48 there was nothing.. so i think it is the cps but i check 2 days ago and it was 500 ohms.... I have noo ideaa

[e30_3I8I]

update scratch the 0 ohms on the cps.. Its 630 ohms.. i think it does need to get replaced?

sounds like ur injectors arnt the problem, all of them wouldnt stop working out of no where, most likely your ecu isnt geting a signal for when to open and close injectors, even though ur geting fuel, doesnt mean its spraying into your intake.

[e30_3I8I]

well i tried a spare ecu and it still was the same.. but when i checked the resistance of the cps it was .630 bently says it should be 540 +- 54 so its way off.

[arty818]

ecu's should be last to blame for no start, theyre built to last. if anything try swaping the cps.

pull the fuel return line and put it in a container, try starting the car and see if fuel flows. if it does and ur car still isnt starting ur injectors arnt recieving a signal, most probably need to replace ur cps. not sure on jetronic cars but i think on motronic (if their the same) your fuel pump wont even run if the ecu isnt recieving data from the cps.

^above is correct. fuel pump will not work if it does not see a cps signal. Injector pulse also comes from the cps.

you can try replacing the CPS first and see if that helps.

Have you checked the main relay is working properly(just because it clicks does not mean it works, you have to test for continuity through it)?

[e30_3I8I]

its getting voltage 12.4-13v around there so its good..

[e30_3I8I]

i bought a new cps from bma and with it not installed in the car . it shows 1000 ohms wtf is up with that?
