i have a 92s10 ext 4.3l tbi 4x4 140,000 mi . well to start a little background ..... bought the truck need a new tranny(so i thought ).
so i put tranny in . ran ok afterwards till i noticed oil pressure drop ... oil pump went out ....soooo i did a motor swap .... ran ok but
when i shut the truck off it wouldn't start ... NO FUEl ... replaced fuel pump .. started fine ... let it set moved it to sell (after charging new battery ) fired right up . found gas leak ... fixed gas leak ....started up no problem drove around pulled back in the driveway ..
shut it off figured i would try to start it back up but not getting fuel ???? anyone give me any ideas to what the problem may be ??????




thanks chevymandan

 

hmmm......not getting any fuel......what kind of pressure r u getting?do u even hear the pump? have u checked all the grounds?

 

Sounds like it only does this when the engine is "hot soaked ??
May have something to do with the pressure regulator bleeding back.
You could try putting on a pressure guage and see if the pressure drops rapidly after the engine was running.

 

well i took the fuel line off at the tbi and getting good pressure......buddie of mine at
parts store had same problem ....had me bring in ignition modual to test...ALL but 1
sector bad .... drove it to work . shut it off . wouldn't start again . worked my 8 hrs ,
come out started right up . coil maybe ???? dunno thru the sepintin belt on the way
home .....

good pressure ... hear the pump well. grounds are all good ..
(had to repair and replace them personally)

 

So the pressure stayed up after you shut off the engine ??

 

so did u replace the ignition module? or r u still running the 1 that came up faulty?

 

i replaced the faulty one , now on hold working on it .....

 

yes it did
