Car not starting

[frozennova]

Car cranks and when I put it into gear and crank at the same time then release clutch (still cranking) it jerks forward but still doesn't start.

Can't hear the buzzing sound after turning ignition before fully turning key to crank.

Suzuki Mehran EFI.

Advice required.

Check for IG coil spark.

[frozennova]

No it's not the ignition.

Pretty certain it's something to do with the fuel pump.

[Hassan1991]

Does fuel pump turns on?
Do you see check light bright up with ignition on?

[frozennova]

I can't hear the pump humming anymore with ignition on.

All lights come on with ignition.

Just filled up tank fully with petrol the last time car was used.

Battery, cranking and ignition spark is very strong also.

[Hassan1991]

Check the fuse of fuel pump.

[frozennova]

What is it called on Mehran EFI?

I couldn't find anything named fuel pump on the fuse box.

[Hassan1991]

Should be called as Fuel pump.
Check cabin fuse box.

[frozennova]

Which one of these is the fuel pump?

[Hassan1991]

Check cabin fuse box as well. I'm not sure about mehran.
Also pump came with relay located right next to main efi relay or it being control my main efi relay

[frozennova]

I believe that is the only fuse box in Mehran.

How would I test the relay?

[Hassan1991]

No where would be one in cabin under drivers foot. Where interior accessories fuses will be.
From the pinout. Turn it on by providing voltages to coils pins and check the connections between NO and Com pins.

[frozennova]

Sorry, could you simplify.
I am not very techincal about cars.

What are NO pins and com pins?
How do I provide voltage to coil pins and from where?
Are coil pins inside the relay?

[Hassan1991]

Here. Pin 85 and 86 are of coils.
Pin 30 is common, 86A is NC (normally close) and 86 NO (normally open).
Have you looked cabin fuse box?

[frozennova]

Sorry, still too advanced for me to understand. I appreciate it though.

The only fuse box I could find in the cabin was the picture I sent earlier.

I managed to get the car running by swapping ignition and fuel pump relays.

Car would sputter to a stop but with accelerator pedal depressed would come to life again.

After a while car started running okay, will I need to replace the relay soon?

Do I need an exact same part number relay, or can I get a slightly different relay? (Advised by shop)

[Hassan1991]

Good.
You can buy brand new same relay.
No need, it's just a simple relay.
There should be a fuse connected with the relay for fuel pump.

[frozennova]

Any idea where I can buy relays in RWP/ISB?

I bought two kabli relays from Saddar yesterday and both weren't of use.

Other shops didn't have stock, and it seems Suzuki dealerships don't either.

One shop was selling a big chunky one saying it would fit, but it was relatively huge so I didn't go for it.

How much do relays cost brand new? Original/china/pakistani?

[Hassan1991]

Check on daraz.
In lahore you can get it from hall road. Also check other online electronic stores. It's an running item.
400-500 for a chinese.
Kabli ones are usually bad because of being sitting for too long, there NO pins get rusted.

[frozennova]

Got new relays.

Would a bad ignition relay cause poor fuel average? Car is drinking about double petrol.
Just installed new relay, would that solve issue?

Also what would cause AC to suddenly stop working? Been a month or so of failure.
Relay is fine, fuse is fine, AC cabin button lights up when pressed.
Can't hear compressor getting engaged when pressing AC button.
