Hi guys, new here. I have a 1997 E320. The problem is the vehicle cranks but does not start. Long story short the injectors are not getting the ground signal. Anyone has any advice?

Things I've cked: fuel pressure, fuel flow, has spark, replaced camshaft position sensor, has voltage to injectors, ohmed crank sensor at 1.10kohms, new battery. The car will run with starting fluid.

Wireharness cked ok. Does anyone have wiring diag for the injectors or the ecu? What inputs does the ecu need to shoot injectors?

Have you checked the CKP sensor (crankshaft position sensor), i had a E300TD with the same fault, also you need diagnostic equipment to check the ECU.

camshaft sensor was replaced. and no check engine codes with diag using scan tool.

looks like you've done a lot of work already. were they done diy or by your indy's recommendation?

i'd look at MAF and o2 sensors next.

I have the same problem on a 1997 E320 it cranks and runs for 20 seconds the most then dies,usually it's more like 2 seconds running,i changed out the cps and it started and ran for almost a minute then just died again,i have fuel pressure and no codes,weird thing is if i step on the gas it instantly dies also i took off the MAF and it looks clean,left the MAF off and started the engine while blocking the intake hose and it ran for as long as i blocked the intake hose,anyone have any ideas?
