Cranks too long before starting, less power, less fuel economy, Sign In

Suzuki Carry Van GA413
1.3 liter 1999 G13bb engine

I picked up a van with less than 100k
When I bought it the CAT was in pieces rolling around inside. I removed the pieces. Has an o2 sensor before the CAT only, none after.
Cranks from 1 to 5 seconds before starting - can't find any consistency whether cold or warm or any other pattern.

When it does eventually start the motor will sometimes jump around for a second or 2 before starting or stalling. I find if I crank it for a second, then stop, then crank again it starts quicker.

This is my third Carry Van and it has roughly 20% less power and 30% less fuel economy.
Exhaust smells like Petrol (No CAT)

Idles a bit rough, nothing crazy though

Engine stalls when fuel is low, not warning light low.

Ive just replaced the spark plugs, leads look good, injectors sound good using the od screwdriver to ear trick.

Any advice on where to start would be greatly appreciated!

What is the fuel pressure when it has the delayed start? Does the rest pressure hold when the fuel pump shuts off?

What kind of fuel system does this have? Is it returnless? If it has a fuel pressure regulator that uses engine vacuum, make sure fuel isn't leaking into the vacuum side of the regulator.

Fuel is first place to look. Check pressure if you can. Try turning key to on, not start for 3 seconds, turn key off. Do this three times. Then try to start. If it starts right up, it may be dirty fuel filter. Checking fuel pressure is most helpful. Bad cam sensors can cause hard starts also, but almost always throws a code.
