Never mention
Yes only these use to power the ecu.

oh man i shud thank you !!! it took quite some time since i have have nerver done nay conversion like this before !!

thank you and the rest people who supported !!

Never mention sir
Glad to know you have done it.

hey bro a problem !!

i only get spark on coil pack 1 and 4 !! 2 and 3 i dont get any !! my engine is not distributor ignition !!
what seems to be the problem ?

pwuser151220154381 (Kanishka Prasad) 2018-02-14 15:35:37 +0500 #105

even the fuel pump doesnt prime !! when wired for the diagram you supplied

pwuser151220154381 (Kanishka Prasad) 2018-02-14 15:59:12 +0500 #106

is it problem with the ecu ? my ecu code is 89661 !!

i connected one end of relay coil to fc pin and other to positive 12 coming from efi relay !! i have all three pins +12v at BATT +B1 and +B !!

i have grounded my fuel pump properly !!

confused with this !!

Check the wiring.
Did pump trip itself if you doesn't start the car?
Your gen 4efe came with distributor. You had done modification?

pwuser151220154381 (Kanishka Prasad) 2018-02-14 16:28:22 +0500 #108

pump doesnt show any sign of working when ignition is on or while cranking !!

my engine came with coil packs not distributors i didnt do any modifications !!

i have check the wiring nothing seems to be the problem !!

pwuser151220154381 (Kanishka Prasad) 2018-02-14 16:37:03 +0500 #109

omg bro ur damn right !! i rechecked the wiring !!! i was soo dumb and i connected the fc pin into the 3 rd pin on ecu connector 2 !! fuel pump works after cranking the engine !!

but still one issue left !!

i only get ignition on cylinder 1 and 4 !! which mean only one coil pack is working !! but ive tested both pack both sees to work fine !!

pwuser151220154381 (Kanishka Prasad) 2018-02-14 16:41:24 +0500 #110

and for the ignition coil packs i didnt even touch the wiring its factory wiring loom

Hassan1991 (Electrical Engineer ) 2018-02-14 16:53:45 +0500 #111

Yes only one pack is working
You have last gen 4efe.
But i think still it's wiring. Any wire is missing.

Hassan1991 (Electrical Engineer ) 2018-02-14 16:54:21 +0500 #112

Ecu got distributor pinouts.

Hassan1991 (Electrical Engineer ) 2018-02-14 16:57:41 +0500 #113

Between firing order is 1~3, 4~2

pwuser151220154381 (Kanishka Prasad) 2018-02-14 17:27:11 +0500 #114

no bro there are two packs !!! this is not distributor ignition !!! my engine is with crank sensor !!

Hassan1991 (Electrical Engineer ) 2018-02-14 17:29:11 +0500 #115

That's the conventional firing order of 4 cylinder engine.
Between try swapping both coils together.

pwuser151220154381 (Kanishka Prasad) 2018-02-14 17:31:01 +0500 #116

no wiring is missing i didnt even touch the factory harness !!

Hassan1991 (Electrical Engineer ) 2018-02-14 17:32:30 +0500 #117

Where you connected distribution and cranking signal wires of ecu?

pwuser151220154381 (Kanishka Prasad) 2018-02-14 17:35:55 +0500 #118

i have a uncut harness coming from coil packs and crank sensors !! to ecu !!

Hassan1991 (Electrical Engineer ) 2018-02-14 17:48:30 +0500 #119

My friend got same ecu with dishwasher variant.
Try swapping coils together. And also use multimeter to check the continuity of the wires.

pwuser151220154381 (Kanishka Prasad) 2018-02-14 17:51:51 +0500 #120

i check continuity and i tries swapping coils also !! when connected the coil 1,4 socket to coil 2,3 then cylinder 2 n 3 gets spark !! both packs are working !!
