Newbie 89 chev truck no fuel problem
hi all , and thank in advance for you help and wisdom. love this site!!
89 chevy 1 ton (30 series) motor home. 350 tbi auto trans.
killed on rough road, in a very remote area. would fire if fuel was dumped into tbi.. i checked fuel pressure and it was a bit low, layed in rain and put in new pump, still no start.
with limited tools and info i determined only 10 volts to the fuel pump at the engine harness,, ALSO. not 1 drop of fuel will come out of injector when cranking.
my hunch is a wiring or computer issue, as it is located behind seat and was not secured.
any help would be appreciated... thank you !

Also if your fuel pressuure switch has gone bad it kills power to your fuel pump..mine died while bouncin around a field its located off the back of the intake behind the distributor..there is also a connector on the lower portion oof the firewall on drivers side if it came unhooked no power to fuel pump

the research i came up with said it does not. also, i do have some voltage to the pump (10 volts) just not enough. when i bypassed and gave the pump 12 volts, i have great pressure but still no tbi spray at all
