Started sputtering on the hwy then cut-out all together and now won't fire-turns over but won't start. I think it's the fuel pump.
If I hook it up to a coder, will it tell me it's the fuel pump?

I read somewhere else on here that the fuel pump is behind the rear passenger seat. Isn't it in the gas tank? If so, how hard is it to drop tank and replace

Thank You!

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
