1995 Suburban 5,7l tbi doesn't start (no fuel and no spark)

[Suburban95]

First: Sorry for my bad Englisch. I am From Germany...

My problem: My 95 Suburban Doesn´t start. I dont get spark from the ignition coil and i dont get fuel from the injektors (The Fuel punp is working) I allready chacked the Wiring and its OK I also checked the resistance of the pickup coil under the Distrubutercab and it has 26 megaohm so i would sey this thing is Bad. Now i have 2 Questions. Can a bad pickup coil kill my spark from the ingition coil and can it kill my fuel from the injektors or is something else wrong ?


I hope i was understandable

I would be very grateful if someone can Help me...

Yes it certainly can. The ECU uses the signal generated at the distributor to fire the injectors. Without that signal the ECU does not know that the engine is turning and does not add any fuel.

^^^ Correct. Failed pickup coil, or failed ignition module would be a common cause of "No spark, no fuel".

26 megohm would be WAY outside the normal spec for a pickup coil.
