Misfires are making me crazy and broke
Soooo.... It's an 04 disco I recently purchased with about 70000 miles. It's missfiring like nobodies business. I changed the coils, plugs, and wires with magnacores and bosch platinums last night. Same rampant missing accompanied by flashing to solid check engine light. Not sure where to go from here. Really need to get this thing running as it's my daily driver for now. I would welcome any advice you may have. Codes from autozone read as follows... p1300, p0308 p0303 p0305 p0302 p0300. I know these are from the same bank. I checked the fuses relays and connection into the side of the coil. I'm lost. Please help.

Thanks for responding, you are the two of the people I was really hoping to hear from.
DiscoMike, I have not checked the fuel pressure, I will get in the rave and try and figure out how to do it today. I only use premium. It's pretty much the same hot or cold, as soon as I start it. When I said bank I must have used the wrong terminology, I was trying to say they're from the same coil.
Savannah, I'll check for arcing tonight and triple check my work when I get home.
If these things check out, crank position sensor? Upstream O2 maybe? I was thinking no on the head gasket because of them being on different sides...and because I might cry if it were a head gasket..... Thoughts...?
O, and any preemptive advice on checking the fuel pressure would be greatly appreciated. I think I saw a fitting for it while I was changing the upper plenum gasket but what tool and where might I find one?
