How do i find my fuel sensor on my 94 safari van tbi motro

SOURCE: no power when hit the gas

The fuel presure should be at least 60- 66 psi key on engine off, and then drop some when started, if it doesn't go any higher than 50 psi that would explain your backfire concern. If it is low then the fuel pump is weak. I have also seen soot on the little wires inside the Mass Airflow Sensor cause a concern like this.

2bbl intake will not fit 87-95 small blocks heads are diferent from pre 86.the center bolts on your manifold are angled different than the front and back bolts.your 2bbl manifold has the same angle bolts front to back.i converted my buddies 89 to carb,had to make adapter plate for carb.but to make a long story short there is a lot of power loss and fuel economy your better of with tbi.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.
