I have 50 psI at the rail and after about 30 minutes it sinks to 40 psi so residual pressure seems good as well

+1 to checking power to injects, and +1 to "proper fuel pressure"(check the damn psi and know exactly...)
We have seen some strange problems with the EWS. Usually there is no light. We have seen crank, no start problems due to flaky keys, this in theory should not happen, but it can and has happened.

Also flaky ignition switches have also caused some unusual problems.

The injectors should have power on one side KOEO (Key On, Engine Off). Some test lights can even flicker a bit on one side of the injectors when the engine is cranking. The DME should be controlling the ground side of the injectors to open them.

fuel pump draw = 5 amps

MS 42.0 and MS 43.0 = 3.5 bar (50.76 +/- 2.9 psi)

residual pressure = >3.0 bar (>43.51 psi)



MS S54 = 5.0 bar (72.5 +/- 2.9 psi)

residual pressure = >4.5 bar (>65.2 psi)


fuel pump delivery volume all models

1.12 liter (1.16 quart) in 30 seconds

Check that plugs are indeed fuel soaked after crank attemps, check a plug for spark with spark plug tester (10 bucks usually connects to plug with plug removed and has ground wire you attach to block and you can see spark in clear chamber, at least the ones i've used. Used caution if engine is flooded with gas or spill overs from fuel rail checks.

OP stated in kind of a convoluted way that the engine started and ran on starting fluid.

This means the engine should have spark from the statement he made.

I skimmmed...saw many recommending fuel pump...consider the fuel filter too. It will get so clogged it'll stop a car...and you could still have fuel pressure when you check it...even through a clogged filter, but enough fuel might not be getting through. If you've never changed it (or either) it's a good time to anyway.

I replaced my fuel pump at something around 200K miles...it was still good...but they fail pretty regularly here.

Did you check fuses in the e-box fuse pack?

Ive read that the ews system sends two signals one to ignition one to fuel injectors. so if anti theft system isnt working it might not be sending a signal to fuel injectors. Im experiencing same problem so thats my next check is signal at fuel injector or out put at ews or dme.... good luck.

I'll be back outside tomorrow playing with it. I hope it's not EWS or something stupid because I just got a new key for the car from the stealer ship last month

how much did that key cost you?? They quoted us 225 bucks crazy right! Took our 325 to a mech and he found a leak in the oil seperater tube and exhuast side cam sensor was bad and it started right up but still have to get a new key. We are also have to find a new instrument cluster to get it back on the road.
