My Q45 wont start. advice is much appreciated

[Tj22]

So long story short I started up my Q, idled it for about 1 to 2 minutes, then tried to pull off from the curb weakly then it shut off like the battery died and I haven't been able to start it since..I don't believe its the fuel pump (i put a new one in about 5 months ago) one time it sounded like it halfway turned over but wouldnt catch. Since then its just an easy crank..I'm thinking maybe coils or something...suggestions

Battery and alternator check first.

I put a brand new battery in the same day as the fuel pump and I replaced the alternator in July

Do you here fuel pump prime when turning key to on?Fuse under dash good?Have gas?Is the relay in trunk clicking?If you crank it see if you can give it gas to make it fire up.

Ok so I figured it out..I have a bad connection with the wiring in the trunk right over the gas tank so the pump is not getting power.....I rigged it up before and forgot about it and when I grabbed the wire I heard the pump hum for a second so I guess somethings fried now..so I'm gonna change the wires and go from there..thanks for your help guys ill continue this forum if there's a further issue
