b2600i spark issue!

i just dropped in the b2600i motor in my 89mazda. i got the harness all pluged in and im not getting any spark to the coil. i had a friend come over with his mazda b2600i. i put my coil and igniter in his truck and it started. so i know their still good. tomorrow im going to put my computer in his truck and see if thats the problem. if not.... im stumped!
the only thing i havent done was swapped the rear half of thre harness that goes from the driver side kick pannel to the rear half of the truck. i know that the electric fuel pump is in the tank but i bought one that splices in the fuel line. it works great! so as of right now theirs still no spark! do you have any ideas or questions?

so the computer is good. it started my friends truck. ive check all of my fuses and their all still good. im stumped... do you have any idea what it could be?

Grounds?

You dont get spark to the coil the coil gives spark to the dist. cap. Did you check for power at the coil and for ground. as the pick up spins inside the dist. it momentarily ground the wire that goes to the coil wich in turns grounds the coil momentarily and colapses the field in the coil and fires to the dist. You need to check to see if you have constant twelve volt feed to the positive side of the coil and ground from the dist. to the negative side of the coil. I tried to put it as simple as possible so hit me up if you cant figure it out i will try and help you as much as possible.

okay so i figured out the spark concern. one of the connections on the wire harness wasnt all the way plugged in all the way. i now have spark. but it still doesnt run. the electric fuel pump that i spliced in doesnt have enough pressure. it was only pumping out 7 psi. and i need 28 to 37 psi.

need to get a fuel pump out of a b2600i or buy a aftermarket pump made for fuel injection

Which harness wasn't plugged in all the way? just wanted to know

I thought b2600i only ran bout 16 lbs of fuel pressure.... maybe im jus mistaken
