Welcome back:

No, that shouldn't cause a problem. Most times, it is either a fuel or ignition spark related issue. You need to check to see if you have both. If you do, then we need to look at timing.
Take a look through this link:

https://www.2carpros.com/articles/car-cranks-but-wont-start

If you want to check the two things I suggested, here are links to guide you:

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

https://www.2carpros.com/articles/how-to-test-an-ignition-system

____________________________________________________________________

Here are the specific directions for testing fuel pressure. The attached pictures correlate with the directions.

CHECKING FUEL PUMP DELIVERY PRESSURE
13 31 029 - Checking fuel pump delivery pressure (N52)

pic 1

Special tools required:
- 13 5 220
- 13 5 221
- 13 5 222

pic 2

Important!
The fuel in the fuel lines is under pressure (approx. 5 bar)!

Catch and dispose of escaping fuel.

pic 3

Necessary preliminary tasks:
- Switch off ignition.
- Remove acoustic cover See: Engine > Removal and Replacement > 11 00 ... Removing and Installing/Replacing Acoustic Cover

pic 4

Remove dust cap (1).

pic 5

Connect special tool kit 13 5 220 (comprising 13 5 221 and 13 5 222) to pressure sensor of DIS Tester.

Connect pressure sensor to DIS Tester.

pic 6

Important!
Do not under any circumstances screw in the check valve up to the mechanical stop.

This could damage the valve in the pressure regulator housing.

pic 7

Mount special tool kit 13 5 220 to injection tube and tighten knurled nut hand-tight.

Screw out check valve (1) so that valve in pressure regulator housing is closed.

Start engine.

Screw in check valve (1) until a pressure reading is indicated on DIS Tester.

pic 8

Measuring fuel pressure.

- Select Measurement.
- Multimeter function appears
- Select Pressure test
- Read off value of fuel pressure.
Compare actual value of test pressure with specified value .

Switch off engine.

Note:
Removing special tool kit 13 5 220:

- Switch off engine
- Screw out check valve fully again.
- Remove special tool kit 13 5 220 from pressure regulator housing.
- Catch and dispose of escaping fuel.

Note:
Read out fault memory of DME control unit.

Check stored fault messages.

Now clear the fault memory.

____________________________________________

I just realized this is for a different vehicle. If you have further questions related to it, I need you to start a new thread. We are trying to keep them specific to one car and problem so it helps others. I'm sorry about that.

Regardless, in the next thread you start, make sure to indicate if you checked these things and what was found.

Take care,
Joe

Remember # one's position on the distributor cap may vary depending on how you install the distributor

Wherever #1 winds up---that is the starting point for the sequence
