Sudden no start

[Dantho0034]

I have a 2000 ranger 4x4 with a 1994 b4000 engine that was swapped to a manual transmission and this truck have been a headhach for about a month now it used to work fine before. started with intermittent no start, replaced crank position sensor everything was back to normal for about 1 week, now after moving the truck in the drive way back to a no spark and no fuel pump.. help

Might be fuel pump fuse blew. Mine does it randomly sometimes, if I hit a dirt mound jus right...I keep spare fuses until I figure it out. Its a big green 30 amp maxi fuse under the hood in the box on the fender.

All the fuse are good, i find it weird that the spark and fuel both let go at the same time

Being that it didn't happen consistently... leads me to believe it's a poor connection. Whether it's ignition switch... EEC relay... or maybe something else is to be diagnosed.

Also forgot to mention when the engine is cranking check engine light stays on, just before it died for good light would flash and i was able to get it going on quick start and it would stay running for about 10minute now just nothing

If the dash lights up as normal and it cranks i would rule out key switch issues.

Possible ECM failure?

Pull the codes

I am not getting any code regarding my probleme, only transmissin code because of the auto to manual swap

While cranking my scanner is not picking up any rpm also

Doesnt that read off the crank sensor?

Id look around that area for a bad wire/connection. Around the cam sensor too

 

[Dantho0034]

Both connector of the Crank sensor is getting continuity to positif post of the battery and reading 1.5v on the voltmeter

 

[Dantho0034]

Would a bad cam sensor mess with the fuel pump?

 

[Uncle Gump]

No

 

[Uncle Gump]

Fuel pump should come on with key on cycle... for a couple seconds.

 

[Dantho0034]

Okk fuel pump stopped cycling when the spark stopped
