No spark help please

[Okanaganranger]

So my 1999 3.0 ranger decided it wanted to die on me last week, I got in it, turned it on, put it in reverse and got about 10 feet. It hasn’t turned over since!! So far I have replaced

-ignition coil
-spark plugs
-spark plug wires
-crankshaft sensor
-camshaft sensor
-all the relays
-even tried a different ECM with pats bypassed

Still I am getting no spark to my plugs. I am getting power to the coil.

Help please!!!

Did you check your battery connections? if they are loose or corroded it wont start. I would start with the basics like the battery voltage and connections.

Battery connections are all good. The engine cranks no problem. It’s getting fuel I hooked a pressure tester to the valve and it’s getting fuel (brand new fuel pump) there is no codes that come up when I plug a reader in.

Still I am getting no spark to my plugs. I am getting power to the coil.

Spark is created when power to the coil primary is switched on and off. The switching is done by the ECM grounding the coil power on/off.

You can usually check this switching with a test light blinking. I'd check the grounding wire connection to the ECM - maybe a broken wire?

 

[Okanaganranger]

I have just rewired the grounds to both sensors now. Took the whole thing out and re ran the ground wires and still nothing.

Did you test for switching primary?

93 no start!

I have a 93, 3.0 manual. I rebuilt the engine, put everything back together, now the fuel pump won't run, and I have no spark, I replaced the Icm and still have the same result, what's my options! Help please.

 

[Rearanger]

what's my options! Help please.

Does this engine have a crank position sensor on the crank pulley?

 

[Ulrichbrett]

No it doesn't
