If so, then look to see if fuel is the problem by removing the cap on the Schrader valve on the fuel rail on top of the injectors. Check to see if the fuse to the fuel pump is good.

If the pump cannot be heard, then replace the cap and lift the hood. Have the helper turn on the key for 3 seconds and off for 5 seconds and on again a couple of times. The computer shuts the power off to the pump if it does not see a signal from the crankshaft sensor. The pump runs for only 2 seconds at a time when the engine is not running. Starting from the basics, take off the fuel cap and listen closely for the fuel pump to come on as a helper turns on the ignition key. There's plenty of room for the factory single exhaust, and the rear axle is miles away from the back of the tank, so if we ever do get a wild itch to add 1-ton axles or huge dual exhaust in this Jeep we know we won't have to make fuel tank modifications to accomplish it.If you feel that the fuel pump has failed, then this is the proper way of diagnosing the problem before replacing an item that may not be needed. But until then, we have the tank up and held in place with four of the eight mounting holes, and we're pleased to say the fit is perfect with no interference at the bottom of the floor. We'll have to drop the tank one more time to finish hooking up our fuel system after the engine swap begins, so we're going to wait until that time to hook up the filler and vent as well as welding the nuts to the inside of the frame to make install and removal much easier.

Then, we pulled the tank back out and finished drilling the holes and then bolted the tank back in. Once it was up tight into place, we measured each side to make sure the tank was centered side to side and from the rear crossmember and then drilled eight small pilot holes through the frame at the center of each tank bracket.
