no sark, has fuel, but injectors are dry

[Joe G]

as the title states. The car is cranking, there is fuel in the rail, but there is no spark.

Help.

Do you have spark?

[nrubenstein]

With no spark and no fuel, look to the DME, or one of the critical sensors (CPS).

First and foremost, do you have a non-EWS DME? (413 red label, for example.)

[Joe G]

CPS is reading 505ohms, and the plug that it connects to shows 3.3volts. That seems awfully low.

The ECU chip was installed backwards by the clown who started and bailed on the build. I flipped it around and that got the fuel pump working, but still no spark or injector fire.

I forget what the DME is, but im 90% sure its not a red label 413

[Adrian_Visser]

If it's a silver label 413 or a 506 you are going to need an EWS delete chip. And did I have epic reading failure or did you edit the OP?

I recommend you check the resistance at the DME connector to make sure you have the right connector hooked up to it. The CPS is pins 43 and 16.

[Joe G]

Who sells EWS delete chips? Its got a turner chip for a bigger MAF and 24lb injectors.

just a read failure.

Pretty sure turner does, Honestly It would be cheaper to find a red label 413 than buy a chip if that is in fact the problem.

And wow, I ken readz good

[Joe G]

ok, thanks. Ill see if i can swap the chip i have from turner for the right one. likely plus some cash.

[Adrian_Visser]

Well how about you make sure that's the problem first. Test the resistance at the DME connector like I suggested.

[Joe G]

according to mike (guy who half assed the swap and then dumped it on me) the chip is an EWS delete chip and its brand new from turner. If that is in fact true, what are other possible reasons for my no fuel injector fire, and no spark issue.

[FredK]

Open the DME and confirm there is a chip.

Then confirm it is plugged in correctly. If it's plugged in backwards, it won't work.

[Joe G]

the chip is there, and it was plugged inn backwards. before i switched it around the fuel pump wasnt running. Once i flipped it the fuel pump turned on, but still no spark. I pulled a coil pack and put in a brand new plug, then grounded it and cranked the car. Its confirmed no spark.

I recommend you check the resistance at the DME connector to make sure you have the right connector hooked up to it. I.e. check the resistance between pins 43 and 16.

[Joe G]

thanks will do! Ill update the thread first thing tomorrow morning.

[Joe G]

if there is no power on pins 43 and 16, what should i check next? same question for if there is power to those pins?
