If the fuel pump relay goes bad your fuel pump will not get power and you will get no fuel. If your fuel pressure is showing too low your pump is either weak and needs to be replaced, your fuel lines are restricted somewhere ( or possibly leaking ) or your fuel filter needs to be replaced.

Is there a Reset button for fuel pump relay on 94 ford e 350?
If there a light on the instrument panel that says fuel cutoff relay that's on, then behind the passenger kick panel is a relay with a red button, push it and if it clicks and the fuel cutoff relay light goes off and you have fuel pressure you should be alright. If the relay doesnt click and the fuel cutoff relay light stays on then you probably have a bad relay. If the light goes out and you don't have any or enough fuel pressure then you need a new fuel pump or fuel filter and or both. also if you don't have enough fuel pressure you could have a bad fuel pressure regulator which is on the back of the engine. If you get the light to go off and it runs good then you have solved the problem. If the light goes out and it starts but does not run very well you should check the fuel pressure. Hope this helps.

Dodge spirit would the transmission has anything to do with the engine turning but not running?
No the trans wouldn't cause it not to run. Unless it was a bad Safety Switch/ Backup Light... if that goes bad the engine wouldn't crank at all... Does it have spark and is it receiving fuel. If no spark check the coil, if the coil is getting no power check the ASD Relay... for Fuel it could still be the ASD, or Fuel Pump, or the Fuel Relay.

How do you check if the fuel pump is bad on a 1999 suburban?
Disconnect the fuel line that goes from the pump to the fuel filter and check for flow - if you get fuel there, the pump is ok. If not, the pump needs to be replaced. If ok, re-connect the fuel line and disconnect the line that comes out of the filter (filter to engine) and checlk for flow. If little or no flow, replace the filter. If filter is ok, reconnect the fuel line and look for an obstruction further up the line. You could also trouble-shoot in reverse by disconnecting the fuel line where it connects at the engine and checking for flow there. Then just work backwards from there.
