03 disco 2 no crank no spark
#14
Replaced fuel pump because I was unsure of maintenance history. Drove fine for 2 days after I bought it. Died while idling. Cranked back up. Wouldn't crank back up after I went to store. Got towed. Cranked after it came off tow truck. Replaced ckp cause of YouTube. Current condition- no fuel pump during ignition, and no spark. Fuel pump components are good.

Jumper the fuel pump relay fuse and see if you have pressure at the test port shrader valve. Oreilly has a pressure test kit you can rent. If you have 50 psi, you can forget fuel pump. If not, that is your problem. If you have fuel pressure, put the old CPS sensor back on and see what you have.

Since you haven't verify fuel pressure, while cranking engine over, we really are just guessing. Until you do that, you could check drivers compartment fuse box, there is a fuse for the coil packs (fuse 14...l believe...but l'm not sure...it will be marked on cover), plus, there is an ignition relay, R4, lower lefthand corner of fuse box, swap it out with similar relay and see if you have spark. Had one Dll where the relay fell out in my hand when l touched it, pushed back in...and rover started right up.
Also, check all of your fuses...the ECM is fused.
